Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies, products, and services. Bitcoin has been criticized for its use in illegal transactions, the large amount of electricity and thus carbon footprint used by mining, price volatility , and thefts from exchanges. Some investors and economists have characterized it as a speculative bubble at various times.

Others have used it as an investment, although several regulatory agencies have issued investor alerts about bitcoin. A few local and national governments are officially using Bitcoin in some capacity, with one country, El Salvador, adopting it as a legal tender. The word bitcoin was defined in a white paper published on 31 October The unit of account of the bitcoin system is the bitcoin. The bitcoin blockchain is a public ledger that records bitcoin transactions.

A network of communicating nodes running bitcoin software maintains the blockchain. Network nodes can validate transactions, add them to their copy of the ledger, and then broadcast these ledger additions to other nodes. To achieve independent verification of the chain of ownership each network node stores its own copy of the blockchain. This allows bitcoin software to determine when a particular bitcoin was spent, which is needed to prevent double-spending.

A conventional ledger records the transfers of actual bills or promissory notes that exist apart from it, but the blockchain is the only place that bitcoins can be said to exist in the form of unspent outputs of transactions. Individual blocks, public addresses and transactions within blocks can be examined using a blockchain explorer.

Transactions are defined using a Forth -like scripting language. When a user sends bitcoins, the user designates each address and the amount of bitcoin being sent to that address in an output. To prevent double spending, each input must refer to a previous unspent output in the blockchain. Since transactions can have multiple outputs, users can send bitcoins to multiple recipients in one transaction.

As in a cash transaction, the sum of inputs coins used to pay can exceed the intended sum of payments. In such a case, an additional output is used, returning the change back to the payer. Though transaction fees are optional, miners can choose which transactions to process and prioritize those that pay higher fees.

The size of transactions is dependent on the number of inputs used to create the transaction, and the number of outputs. The blocks in the blockchain were originally limited to 32 megabytes in size. The block size limit of one megabyte was introduced by Satoshi Nakamoto in Eventually the block size limit of one megabyte created problems for transaction processing, such as increasing transaction fees and delayed processing of transactions.

In the blockchain, bitcoins are registered to bitcoin addresses. Creating a bitcoin address requires nothing more than picking a random valid private key and computing the corresponding bitcoin address. This computation can be done in a split second. But the reverse, computing the private key of a given bitcoin address, is practically unfeasible.

Moreover, the number of valid private keys is so vast that it is extremely unlikely someone will compute a key-pair that is already in use and has funds. The vast number of valid private keys makes it unfeasible that brute force could be used to compromise a private key. To be able to spend their bitcoins, the owner must know the corresponding private key and digitally sign the transaction.

If the private key is lost, the bitcoin network will not recognize any other evidence of ownership; [27] the coins are then unusable, and effectively lost. To ensure the security of bitcoins, the private key must be kept secret. Regarding ownership distribution, as of 16 March , 0. Mining is a record-keeping service done through the use of computer processing power. To be accepted by the rest of the network, a new block must contain a proof-of-work PoW. By adjusting this difficulty target, the amount of work needed to generate a block can be changed.

Every 2, blocks approximately 14 days given roughly 10 minutes per block , nodes deterministically adjust the difficulty target based on the recent rate of block generation, with the aim of keeping the average time between new blocks at ten minutes. In this way the system automatically adapts to the total amount of mining power on the network.

The proof-of-work system, alongside the chaining of blocks, makes modifications of the blockchain extremely hard, as an attacker must modify all subsequent blocks in order for the modifications of one block to be accepted. Computing power is often bundled together by a Mining pool to reduce variance in miner income. Individual mining rigs often have to wait for long periods to confirm a block of transactions and receive payment.

In a pool, all participating miners get paid every time a participating server solves a block. This payment depends on the amount of work an individual miner contributed to help find that block. The successful miner finding the new block is allowed by the rest of the network to collect for themselves all transaction fees from transactions they included in the block, as well as a pre-determined reward of newly created bitcoins.

The bitcoin protocol specifies that the reward for adding a block will be reduced by half every , blocks approximately every four years. Eventually, the reward will round down to zero, and the limit of 21 million bitcoins [h] will be reached c. Bitcoin is decentralized thus: [7].

Conversely, researchers have pointed out at a "trend towards centralization". Although bitcoin can be sent directly from user to user, in practice intermediaries are widely used. The pool has voluntarily capped their hashing power at According to researchers, other parts of the ecosystem are also "controlled by a small set of entities", notably the maintenance of the client software, online wallets and simplified payment verification SPV clients.

Bitcoin is pseudonymous , meaning that funds are not tied to real-world entities but rather bitcoin addresses. Owners of bitcoin addresses are not explicitly identified, but all transactions on the blockchain are public. In addition, transactions can be linked to individuals and companies through "idioms of use" e.

Wallets and similar software technically handle all bitcoins as equivalent, establishing the basic level of fungibility. Researchers have pointed out that the history of each bitcoin is registered and publicly available in the blockchain ledger, and that some users may refuse to accept bitcoins coming from controversial transactions, which would harm bitcoin's fungibility. Gox froze accounts of users who deposited bitcoins that were known to have just been stolen.

A wallet stores the information necessary to transact bitcoins. While wallets are often described as a place to hold [61] or store bitcoins, due to the nature of the system, bitcoins are inseparable from the blockchain transaction ledger. A wallet is more correctly defined as something that "stores the digital credentials for your bitcoin holdings" and allows one to access and spend them. The first wallet program, simply named Bitcoin , and sometimes referred to as the Satoshi client , was released in by Satoshi Nakamoto as open-source software.

There are several modes which wallets can operate in. They have an inverse relationship with regards to trustlessness and computational requirements. Third-party internet services called online wallets or webwallets offer similar functionality but may be easier to use. In this case, credentials to access funds are stored with the online wallet provider rather than on the user's hardware.

A malicious provider or a breach in server security may cause entrusted bitcoins to be stolen. An example of such a security breach occurred with Mt. Gox in Wallet software is targeted by hackers because of the lucrative potential for stealing bitcoins.

A hardware wallet is a computer peripheral that signs transactions as requested by the user. These devices store private keys and carry out signing and encryption internally, [72] and do not share any sensitive information with the host computer except already signed and thus unalterable transactions.

The user sets a passcode when setting up a hardware wallet. A paper wallet is created with a keypair generated on a computer with no internet connection ; the private key is written or printed onto the paper [i] and then erased from the computer.

Physical wallets can also take the form of metal token coins [75] with a private key accessible under a security hologram in a recess struck on the reverse side. The domain name bitcoin. On 3 January , the bitcoin network was created when Nakamoto mined the starting block of the chain, known as the genesis block.

The receiver of the first bitcoin transaction was Hal Finney , who had created the first reusable proof-of-work system RPoW in Blockchain analysts estimate that Nakamoto had mined about one million bitcoins [94] before disappearing in when he handed the network alert key and control of the code repository over to Gavin Andresen. Andresen later became lead developer at the Bitcoin Foundation. This left opportunity for controversy to develop over the future development path of bitcoin, in contrast to the perceived authority of Nakamoto's contributions.

After early " proof-of-concept " transactions, the first major users of bitcoin were black markets , such as Silk Road. During its 30 months of existence, beginning in February , Silk Road exclusively accepted bitcoins as payment, transacting 9. The Bitcoin Foundation was founded in September to promote bitcoin's development and uptake. On 1 November , the reference implementation Bitcoin-Qt version 0.

It introduced a front end that used the Qt user interface toolkit. Developers switched to LevelDB in release 0. The fork was resolved shortly afterwards. From version 0. Transaction fees were reduced again by a factor of ten as a means to encourage microtransactions. Version 0. In March the blockchain temporarily split into two independent chains with different rules due to a bug in version 0.

The two blockchains operated simultaneously for six hours, each with its own version of the transaction history from the moment of the split. Normal operation was restored when the majority of the network downgraded to version 0. As a result, this blockchain became the longest chain and could be accepted by all participants, regardless of their bitcoin software version. The US Financial Crimes Enforcement Network FinCEN established regulatory guidelines for "decentralized virtual currencies" such as bitcoin, classifying American bitcoin miners who sell their generated bitcoins as Money Service Businesses MSBs , that are subject to registration or other legal obligations.

In April, exchanges BitInstant and Mt. On 15 May , US authorities seized accounts associated with Mt. This marked the first time a government agency had seized bitcoin. On 5 December , the People's Bank of China prohibited Chinese financial institutions from using bitcoins. Release 0. It introduced a consensus library which gave programmers easy access to the rules governing consensus on the network. In version 0. In July , the CheckSequenceVerify soft fork activated.

In October , Bitcoin Core's 0. Research produced by the University of Cambridge estimated that in , there were 2. Segwit was intended to support the Lightning Network as well as improve scalability. China banned trading in bitcoin, with first steps taken in September , and a complete ban that started on 1 February In September , an anonymous party discovered and reported an invalid-block denial-of-server vulnerability to developers of Bitcoin Core, Bitcoin ABC and Bitcoin Unlimited.

Further analysis by bitcoin developers showed the issue could also allow the creation of blocks violating the 21 million coin limit and CVE - was assigned and the issue resolved. Bitcoin prices were negatively affected by several hacks or thefts from cryptocurrency exchanges, including thefts from Coincheck in January , Bithumb in June, and Bancor in July.

The IMF also warned that it would be difficult to get a loan from the institution. Also In June, the Taproot network software upgrade was approved, adding support for Schnorr signatures , improved functionality of Smart contracts and Lightning Network. On 25 March Pavel Zavalny stated that Russia might accept bitcoin for payment for oil and gas exports, in response to sanctions stemming from the Russian invasion of Ukraine.

Satoshi Nakamoto stated in an essay accompanying bitcoin's code that: "The root problem with conventional currencies is all the trust that's required to make it work. The central bank must be trusted not to debase the currency, but the history of fiat currencies is full of breaches of that trust.

According to the European Central Bank , the decentralization of money offered by bitcoin has its theoretical roots in the Austrian school of economics , especially with Friedrich von Hayek in his book Denationalisation of Money: The Argument Refined , [] in which Hayek advocates a complete free market in the production, distribution and management of money to end the monopoly of central banks.

According to The New York Times , libertarians and anarchists were attracted to the philosophical idea behind bitcoin. Early bitcoin supporter Roger Ver said: "At first, almost everyone who got involved did so for philosophical reasons.

We saw bitcoin as a great idea, as a way to separate money from the state. Nigel Dodd argues in The Social Life of Bitcoin that the essence of the bitcoin ideology is to remove money from social, as well as governmental, control.

The declaration includes a message of crypto-anarchism with the words: "Bitcoin is inherently anti-establishment, anti-system, and anti-state. Bitcoin undermines governments and disrupts institutions because bitcoin is fundamentally humanitarian. David Golumbia says that the ideas influencing bitcoin advocates emerge from right-wing extremist movements such as the Liberty Lobby and the John Birch Society and their anti-Central Bank rhetoric, or, more recently, Ron Paul and Tea Party -style libertarianism.

It takes control back from central authorities. It's revolutionary. A study of Google Trends data found correlations between bitcoin-related searches and ones related to computer programming and illegal activity, but not libertarianism or investment topics. Bitcoin is a digital asset designed to work in peer-to-peer transactions as a currency. Economists define money as serving the following three purposes: a store of value , a medium of exchange , and a unit of account.

Shiller writes that bitcoin has potential as a unit of account for measuring the relative value of goods, as with Chile's Unidad de Fomento , but that "Bitcoin in its present form [ According to research by Cambridge University , between 2. The number of users has grown significantly since , when there were ,—1. The overwhelming majority of bitcoin transactions take place on a cryptocurrency exchange , rather than being used in transactions with merchants.

Prices are not usually quoted in units of bitcoin and many trades involve one, or sometimes two, conversions into conventional currencies. In and bitcoin's acceptance among major online retailers included only three of the top U. Bitcoin is "not actually usable" for retail transactions because of high costs and the inability to process chargebacks , according to Nicholas Weaver, a researcher quoted by Bloomberg.

High price volatility and transaction fees make paying for small retail purchases with bitcoin impractical, according to economist Kim Grauer. However, bitcoin continues to be used for large-item purchases on sites such as Overstock. Bitcoins can be bought on digital currency exchanges.

Per researchers, "there is little sign of bitcoin use" in international remittances despite high fees charged by banks and Western Union who compete in this market. In , the National Australia Bank closed accounts of businesses with ties to bitcoin, [] and HSBC refused to serve a hedge fund with links to bitcoin. On 10 December , the Chicago Board Options Exchange started trading bitcoin futures, [] followed by the Chicago Mercantile Exchange , which started trading bitcoin futures on 17 December The request was motivated by oil company's goal to pay its suppliers.

Velde, Senior Economist at the Chicago Fed , described bitcoin as "an elegant solution to the problem of creating a digital currency". Louis , stated that bitcoin is a threat to the establishment, which he argues is a good thing for the Federal Reserve System and other central banks , because it prompts these institutions to operate sound policies. The Winklevoss twins have purchased bitcoin.

Other methods of investment are bitcoin funds. The first regulated bitcoin fund was established in Jersey in July and approved by the Jersey Financial Services Commission. Forbes named bitcoin the best investment of According to bitinfocharts. The price of bitcoins has gone through cycles of appreciation and depreciation referred to by some as bubbles and busts. According to Mark T. Unusual for an asset, bitcoin weekend trading during December was higher than for weekdays. Because of bitcoin's decentralized nature and its trading on online exchanges located in many countries, regulation of bitcoin has been difficult.

However, the use of bitcoin can be criminalized, and shutting down exchanges and the peer-to-peer economy in a given country would constitute a de facto ban. Regulations and bans that apply to bitcoin probably extend to similar cryptocurrency systems. The U. Commodity Futures Trading Commission has issued four "Customer Advisories" for bitcoin and related investments. Securities and Exchange Commission warned that investments involving bitcoin might have high rates of fraud, and that investors might be solicited on social media sites.

The European Banking Authority issued a warning in focusing on the lack of regulation of bitcoin, the chance that exchanges would be hacked, the volatility of bitcoin's price, and general fraud. An official investigation into bitcoin traders was reported in May Justice Department launched an investigation into possible price manipulation, including the techniques of spoofing and wash trades.

Following the first delivery date in January , the CME requested extensive detailed trading information but several of the exchanges refused to provide it and later provided only limited data. The Commodity Futures Trading Commission then subpoenaed the data from the exchanges. State and provincial securities regulators, coordinated through the North American Securities Administrators Association , are investigating "bitcoin scams" and ICOs in 40 jurisdictions.

Academic research published in the Journal of Monetary Economics concluded that price manipulation occurred during the Mt Gox bitcoin theft and that the market remains vulnerable to manipulation. Research by John M. Griffin and Amin Shams in suggests that trading associated with increases in the amount of the Tether cryptocurrency and associated trading at the Bitfinex exchange account for about half of the price increase in bitcoin in late El Salvador officially adopted Bitcoin as legal tender, in the face of internal and international criticism, becoming the first nation to do so.

Ukraine is officially using Bitcoin to collect donations to fund the resistance against the Russian invasion. Iran announced pending regulations that would require bitcoin miners in Iran to sell bitcoin to the Central Bank of Iran , and the central bank would use it for imports. In Switzerland , the Canton of Zug accepts tax payments in bitcoin.

Bitcoin, along with other cryptocurrencies, has been described as an economic bubble by at least eight Nobel Memorial Prize in Economic Sciences laureates, including Robert Shiller , [] Joseph Stiglitz , [] and Richard Thaler. Journalists, economists, investors, and the central bank of Estonia have voiced concerns that bitcoin is a Ponzi scheme. Bitcoin wealth is highly concentrated, with 0. Bitcoin has been criticized for the amount of electricity consumed by mining.

The development of intermittent renewable energy sources , such as wind power and solar power , is challenging because they cause instability in the electrical grid. Several papers concluded that these renewable power stations could use the surplus energy to mine Bitcoin and thereby reduce curtailment , hedge electricity price risk , stabilize the grid, increase the profitability of renewable energy infrastructure, and therefore accelerate transition to sustainable energy and decrease Bitcoin's carbon footprint.

Concerns about bitcoin's environmental impact relate bitcoin's energy consumption to carbon emissions. The results of recent studies analyzing bitcoin's carbon footprint vary. Bitcoins annual e-waste is estimated to be about 30 metric tons as of May , which is comparabe to the small IT equipment waste produced by the Netherlands.

One Bitcoin generates g of e-waste per transaction. The average lifespan of Bitcoin mining devices is estimated to be only 1. The use of bitcoin by criminals has attracted the attention of financial regulators, legislative bodies, law enforcement, and the media. Several news outlets have asserted that the popularity of bitcoins hinges on the ability to use them to purchase illegal goods. Bitcoin Core is free and open-source software that serves as a bitcoin node the set of which form the bitcoin network and provides a bitcoin wallet which fully verifies payments.

It is considered to be bitcoin's reference implementation. Bitcoin Core includes a transaction verification engine and connects to the bitcoin network as a full node. It does not facilitate the buying or selling of bitcoin. It allows users to generate QR codes to receive payment. The software validates the entire blockchain , which includes all bitcoin transactions ever. This distributed ledger which has reached more than gigabytes in size as of Jan , must be downloaded or synchronized before full participation of the client may occur.

It also provides access to testnet, a global testing environment that imitates the bitcoin main network using an alternative blockchain where valueless "test bitcoins" are used. Regtest or Regression Test Mode creates a private blockchain which is used as a local testing environment.

Checkpoints which have been hard coded into the client are used only to prevent Denial of Service attacks against nodes which are initially syncing the chain. For this reason the checkpoints included are only as of several years ago. This limited the maximum network capacity to about three transactions per second. A network alert system was included by Satoshi Nakamoto as a way of informing users of important news regarding bitcoin.

It had become obsolete as news on bitcoin is now widely disseminated. Bitcoin Core includes a scripting language inspired by Forth that can define transactions and specify parameters. Two stacks are used — main and alt. Looping is forbidden. Bitcoin Core uses OpenTimestamps to timestamp merge commits.

The original creator of the bitcoin client has described their approach to the software's authorship as it being written first to prove to themselves that the concept of purely peer-to-peer electronic cash was valid and that a paper with solutions could be written. The lead developer is Wladimir J. Andresen left the role of lead developer for bitcoin to work on the strategic development of its technology.

A person who does this is known as a Hodler. In Charles Stross ' science fiction novel, Neptune's Brood , the universal interstellar payment system is known as "bitcoin" and operates using cryptography. Bitcoin was obscure back then, and I figured had just enough name recognition to be a useful term for an interstellar currency: it'd clue people in that it was a networked digital currency. The documentary The Rise and Rise of Bitcoin portrays the diversity of motives behind the use of bitcoin by interviewing people who use it.

These include a computer programmer and a drug dealer. Each of the eight members represented a cryptocurrency, including Bitcoin, Ethereum and Cardano. It covers studies of cryptocurrencies and related technologies, and is published by the University of Pittsburgh.

This is the case even if you use your crypto to pay for a purchase. Multiple companies have proposed crypto ETFs, including Fidelity, but regulatory hurdles have slowed the launch of any consumer products. As of June , there are no ETFs available to average investors on the market. You can buy cryptocurrencies through crypto exchanges , such as Coinbase , Kraken or Gemini.

In addition, some brokerages, such as WeBull and Robinhood, also allow consumers to buy cryptocurrencies. Kat Tretina is a freelance writer based in Orlando, FL.

Our estimation results suggest that BitCoin attractiveness indicators are the strongest drivers of BitCoin price followed by market forces. In contrast, macro-financial developments do not determine BitCoin price in the long-run.

Our findings suggest that as long as BitCoin price will be mainly driven by speculative investments, BitCoin will not be able to compete with standard currencies. The most successful among them is BitCoin, both in terms of its impressive growth in the number of currency users and popularity by retailers. Since its introduction in , BitCoin has been characterized also by a phenomenal increase in the number of transactions and market capitalization, which surpassed 5 billion US dollar in and since then has recorded further growth.

In the public media and in scientific community there is ongoing a lively debate on wheather BitCoin can actually function as a substitute for standard currencies such as US dollar, Euro or Yen. There are two competing views in the literature on whether BitCoin fulfils the three criteria of a currency a medium of exchange, a unit of account, and a store of value Mankiw One part of the literature argues that BitCoin does not behave as a real currency, but rather resembles speculative investments e.

Velde ; Hanley ; Yermack ; Williams Other line of research, stresses the positive aspects of BitCoin and perceives it as a global virtual currency with strong future potential e. Plassaras ; Satran ; Luther and White ; Folkinshteyn et al. Also from a legal point of view, there is no global agreement on the status of BitCoin, as there are no international laws regulating BitCoin. Each country regards BitCoin differently and regulations are constantly evolving.

Finland considers BitCoin as priced commodity. Germany has recognized it as private currency. Yet other EU Member States by and large are in the wait-and-see stage. In light of these and other open questions about BitCoin, in April the European Commission organized a Virtual Currencies Conference, Footnote 1 where among others the potential and challenges of BitCoin to become a global currency were discussed.

The Virtual Currencies Conference acknowledged the need for further research to better understand the socio-economic and monetary aspects of the virtual currency ecosystem. In order to shed light on these and related questions, the present paper attempts to identify and analyze BitCoin features which may facilitate BitCoin to become a global currency, as well as characteristics which may impede the use of BitCoin as a medium of exchange, a unit of account, or a store of value.

Among the BitCoin features, which may facilitate its use as a currency, we have identified low transaction costs, high anonymity and privacy, learning spillover effects, infinite divisibility and no inflationary pressures. Among the BitCoin features, which may impede its use as a currency include the absence of a legal tender attribute, difficulty to procure BitCoins, relatively high fixed costs of adoption, dependence on network externalities, absence of an institution enforcing dispute resolution, absence of BitCoin denominated credits, deflationary pressure, extremely high price volatility, and issues with cyber security.

Our second contribution to the literature is to undertake a comparative analysis of the identified BitCoin features with traditional currencies and their possible impact on BitCoin functions as a currency. Our analysis builds on previous studies, which have identified several advantages of BitCoin over traditional currencies. These costs can be substantial for standard currencies. Similarly, an advantage of BitCoin is that it is more convenient than standard payment mechanisms for small-value purchases, as it allows for money transfers at low costs and relatively fast Hayes et al.

As noted by Folkinshteyn et al. In contrast, Grinberg opposes this view and argues that the response of the traditional e-commerce sector to the competitive pressure from BitCoin may induce them to reduce their transaction costs and thus offset the advantage of BitCoin, while providing also other benefits such as higher security.

Second, an additional advantage of BitCoin, compared to standard currencies, is that it may reduce opportunities for theft, such as bank robbery. BitCoin could help curtail vandalism of vending machines, public phones, etc. Similarly, businesses who handle cash, such as taxi drivers and small shops, could be much less vulnerable to robbery, if they would use BitCoin. Finally, BitCoin is a global currency, implying that there are no transaction costs related to currency exchange.

On the other hand, BitCoin faces several challenges compared to standard currencies. Given that BitCoin transactions take place exclusively over the internet, cyber-security is its main threat. Particularly vulnerable to cyber-attacks are large holdings of BitCoins as well as BitCoin exchanges.

The security problem is largely attributed to the lack of an oversight institution that would ensure security of BitCoin transactions and BitCoin system ECB ; Plassaras ; Moore and Christin Second, the use of a new currency, such as BitCoin, requires an initial investment for both businesses and consumers Velde This includes costs linked to getting acquainted with BitCoin system in general and to the adoption of the payment technology in particular.

For example, BitCoin requires the use of electronic devices including specific software. Similarly, BitCoin may also suffer from information asymmetry, as its system is relatively complex and therefore may not be easily understood by all potential users ECB Third, Yermack argues that BitCoin may fail to become a global medium of exchange, as it is used in too few exchanges of goods and services; it has a negligible market presence globally.

Currently, there are around 0. For example, if compared to million conventional payments and terminal transactions per day done in Europe alone, the market share of BitCoin appears to be minuscule EBA Fourth, Yermack argues that BitCoin is ineffective as a tool of risk management of price volatility as it is uncorrelated with major world currencies i.

US dollar, Euro, Yen, British Pound or gold price, which is a common use of currencies by businesses for hedging the risks associated with currency volatility. Macroeconomic changes that cause adjustment in exchange rates of currencies are not reflected in any way in BitCoin price movements implying that its price volatility cannot be easily hedged.

Finally, BitCoin faces the problem of network externalities in its adoption Gowrisankaran and Stavins , as its benefit in exchange is positively correlated with the number of users Plassaras ; ECB Among all BitCoin features that we have identified and analyzed, eventually, price volatility is the one with the largest differences compared to standard currencies, such as US dollar, Euro, Yen, British Pound. As shown in Fig. One consequence of such extreme price volatility is a threat for BitCoin being accepted as a global currency, as it may fail to accurately convey relative prices of goods and services in the economy and may generate uncertainties to its holders due to its inability to preserve stable value over time.

Indeed, a desirable property of any monetary mean is that it holds its value over short-to-medium periods of time, in order not to create distortion when used as a medium of exchange in transactions, a unit of account, and a store of value. Large price movements alter the purchasing power by causing risk and costs to firms and consumers using BitCoin. Given that BitCoin is a relatively new currency, its price formation is not well understood yet, as there are only few studies on BitCoin price formation available in the literature e.

Buchholz et al. In order to better understand the reasons for such extremely high price volatility, we attempt to identify drivers of BitCoin price and estimate their importance econometrically. This is our third contribution to the literature. Previous studies e. We apply time-series analytical mechanisms to these drivers using daily data for the — period. Our estimation results suggest that BitCoin attractiveness variables are most important drivers of BitCoin price followed by market forces.

Our estimates do not support previous findings that macro-financial developments are driving BitCoin price in the long-run. Generally, our findings suggest that as long as BitCoin price will be mainly driven by speculative investments, BitCoin will not be able to compete with standard currencies. The rest of the paper is structured as follows. Section 2 provides background information about BitCoin, which is a relatively new virtual currency.

In the context of the three currency criteria, the key features are discussed and contrasted with standard currencies to analyze whether BitCoin fulfills the main functions of money. Section 3 identifies the main factors affecting BitCoin price based on previous studies; outlines the econometric approach—a Vector Auto Regressive VAR model—and specifies the estimated model. The final section concludes. Currency, or money in general, is typically defined as having three main functions: a medium of exchange, a unit of account, and a store of value Mankiw Among different types of currencies, virtual currencies are clearly distinguished from fiat currencies i.

The most popular virtual currency is BitCoin, created by the Japanese programmer Satoshi Nakamoto in Nakamoto It was the first open source virtual currency, as BitCoin is managed by an open source software algorithm that uses the global internet network both to create BitCoins as well as to record and verify its transactions.

Being a cryptocurrency, BitCoin uses the principles of cryptography to control the creation and exchange of BitCoins. BitCoins can be stored in local wallets e. Compared to standard fiat currencies, such as US dollars or Euro, a distinguishing feature of BitCoin is that the quantity of units in circulation is not controlled by a person, group, company, central authority, or government, but by a software algorithm. In return for this service they receive transaction fees and newly minted BitCoins.

A fixed amount of BitCoins is issued at a constant a priori defined and publicly known rate, according to which the stock of BitCoins increases at a decreasing rate. In the growth rate of BitCoin will converge to zero, when the maximum amount of BitCoins in circulation will reach 21 million units; according to the current algorithm it will not change after BitCoin does not have physical representation. Instead, it is stored either on electronic devices e.

BitCoins can be spent on both goods and services, if accepted by the retailer. Users interact with each other directly and anonymously, without third-party intervention. There is neither a central clearing house nor any other intermediary institution involved in the transactions such as central bank or government agency Table 1.

Currently, BitCoins can be acquired either 1 by exchanging them for standard money e. US dollar, Euro on a BitCoin exchange or from a BitCoin dealer, 2 by obtaining them from sales of goods or services denominated in BitCoin, or 3 through a mining process Plassaras ; CoinDesk c.

BitCoins can be used to buy goods or services worldwide, provided that the transaction partner accepts BitCoin as a mean of payment. A transaction implies that the present owner of BitCoins transfers the ownership of a certain amount of BitCoins to a different market participant in exchange for other currencies, goods or services. A continuously growing number of companies accept BitCoins as payments for their goods and services, at the beginning of there were more than , venues accepting BitCoins CoinDesk a ; Cuthbertson There are two competing views in the literature on whether BitCoin fulfils the three criteria of a currency a medium of exchange, a unit of account, and a store of value.

One part of the literature argues that BitCoin does not behave largely like a real currency, as it does not fulfil the main functions of a currency, but rather serves as a vehicle for speculative investments Velde ; Hanley ; Yermack ; Williams Other line of research stresses the potential of BitCoin and perceives it as a global currency with strong future potential e.

In the following we attempt to identify and analyze the most important advantages and disadvantages of BitCoin in the context of the three currency functions. One of the main functions of any currency is to intermediate the exchange of goods and services. We identify several features of BitCoin as a medium of exchange, which differ substantially from traditional currencies: transaction costs, anonymity and transparency, legal tender, fixed costs, network externalities, dispute resolution, and credit market see Table 2 for summary.

An appealing feature of BitCoin when used as a medium of exchange is its comparative advantage in transaction costs relative to standard currencies, as BitCoin transaction fees are considerably lower than comparable costs of traditional means of payment e. BitCoin transaction fees cover only the costs of maintaining the system i.

Footnote 3 Transaction costs of standard currencies are considerably higher as they need to cover all costs of intermediaries. Besides the costs of clearing system, the fees charged for standard money transfers need to also offset the cost of storage, authentication, transport, security, etc. Footnote 4 Further, BitCoin offers faster transaction execution than traditional online payment systems.

We may conclude that comparably low transaction and maintenance costs together with fast execution of transactions may facilitate the acceptance and use of BitCoin as a currency Table 2. An area, where BitCoin has a relatively high appeal, involves exchanges linked to illegal and criminal activities e. While this was not the intent of BitCoin creators, it is rather the way individuals choose to use it, as certain BitCoin characteristics give its predisposition to be advantageous in such activities.

For example, BitCoin payment transactions are anonymous and do not require the provision of personal identity information. Further, BitCoin allows for easy international transfers e. With its infrastructure being spread across the globe, it is difficult to intercept individual transactions Bryans ; EBA These features grant BitCoin a rather high predisposition to be used in illegal activities. For example, the internet portal Silk Road , created in January , provided online marketplace for the sale of illegal narcotics and weapons using BitCoins for payment, accounting for as much as half of all BitCoin transactions.

Silk Road was shut down following an FBI investigation in Gambling is other area where BitCoin appears to be growing as a medium of exchange, as it protects costumer privacy and allows receiving funds from consumers not being able to use other payment methods.

Generally, there is a growing number of online gambling sites, the BitCoin Wiki lists around BitCoin based casinos, poker sites, bingo games, betting services and lotteries. The BitCoin platform is transparent and public, meaning that anyone is able to follow the chain of transaction. All BitCoin payments have a traceable history that can be viewed by anyone.

For example, the knowledge of the identity of any user from any transaction e. Hence, BitCoin system is often referred as pseudonymous in the sense that full history of all transactions and every BitCoin is preserved on the publicly ledger. We may conclude that relatively high anonymity of BitCoin users and transparency of BitCoin transactions may facilitate the popularity and use of BitCoin as a currency Table 2. One distinguishing feature of BitCoin is that it is not a legal tender as opposed to standard currencies which would imply its mandatory acceptance in exchanges.

Private or public businesses are not legally obliged to accept BitCoin as a payment form for goods and services they trade. The use of BitCoin as a medium of exchange is thus fully dependent on its voluntary adoption by market participants EBA According to Yermack , an additional obstacle for BitCoin to become a widely used medium of exchange, arises from the difficulty of procuring new BitCoins.

BitCoins can be obtained only from online exchanges or dealers except for successful BitCoin miners. The use of a new currency, such as BitCoin, requires an initial investment for both businesses and consumers. This includes costs linked to getting acquainted with the BitCoin system in general and to the adoption of the payment technology in particular.

Footnote 5. In addition, a relatively high level of computer knowledge is required for understanding and using BitCoins, which may represent a barrier to many potential users and may constraint its wider adoption i. BitCoin is based on a complex code, which is understood by only a few persons and is controlled by even fewer individuals programmers , who oversee the whole system without accountability, arbitration or recourse Velde ; Yermack We may conclude that in presence of high fixed costs, the popularity and use of BitCoin as a currency may be seriously impeded at least in the short-run, as currently the technical knowledge about BitCoin is still rather low in society.

However, BitCoin may generate some additional benefits to its users through learning spillover effects Table 2. The incentives for market participants to use BitCoin depend on the number of existing users. That is, the benefit of making the investment and using it in exchanges depends on the number of other suppliers and consumers of goods and services using BitCoin.

If only a few businesses accept BitCoins, there are little incentives for consumers to acquire them. On the other hand, if only a few consumers use BitCoins, businesses have little incentives to invest into the equipment for processing BitCoin payments for their goods and services. This is a well-known problem of network externalities Gowrisankaran and Stavins Hence, one of the main BitCoin challenges in becoming a global currency is to convince users to use it in their purchases and businesses to accept it as payment form for their goods and services Berentsten ; ECB ; Plassaras Yermack argues that BitCoin largely fails to be a global medium of exchange as it is used to a limited extent to intermediate the exchange of goods and services.

Currently there are around 0. According to BlockChain , the use of BitCoin as a medium of exchange is continuously increasing over time as more and more businesses tend to accept it as a form of payment. Hence, despite the rather low BitCoin penetration in the global exchanges currently may not be an obstacle for BitCoin to become a global medium of exchange in future. First, given that BitCoin is a relatively new currency, it may take some time till it gets adopted in a wider context.

Second, there exist examples of small countries with own currencies e. Fiji which intermediate the exchange of goods and services within the national boundaries but have only a minor share globally. We may conclude that the issue of network externalities may impede growth of BitCoin use as a currency in the short-run. However, these issues may become less relevant in future, as BitCoin use continuously increases Table 2.

The use of BitCoin in market exchanges bears a certain risk, because of the absence of any protection against disputes between parties involved in the exchange. Once a BitCoin transaction is realized, it is irreversible and cannot be disputed. There is no centralized mechanism available to revert an erroneous transaction or to handle the disputes with the aim to provide protection against human errors of fraud that may occur in exchanges e.

We may conclude that the absence of an institution regulating and enforcing BitCoin related disputes, the popularity and use of BitCoin as a currency may be impeded, particularly for risk-averse market participants Table 2.

Another obstacle for BitCoin to become a widely used medium of exchange may be that BitCoin cannot be used to take loans because, under the current system, every loan would need to be made in BitCoin. Whereas the basis of standard banking system is fractional-reserve, which determine how much new money can be created through loans, BitCoins are unique and cannot be duplicated, they only exist as an electronic analog a kind of physical coin.

This limits the expansion of BitCoin Hanley For example, the absence of BitCoin denominated credit cards and consumer loans do not allow purchases on credit—a method widely used in most developed retail markets, which limits the expansion of BitCoin as a medium of exchange Yermack We may conclude that in the absence of BitCoin denominated credit, BitCoin growth is seriously constrained, as the share of credit transactions is rather high and growing in modern societies Table 2.

To serve the function of a unit of account, as any other currency, BitCoin should be able to measure the relative value of goods and services and other transactions e. We identify two key characteristics of BitCoin as a unit of account, which differ substantially from traditional currencies: divisibility and price volatility see Table 2 for summary.

An important distinguishing feature of BitCoin is its nearly infinite divisibility, implying that prices may be quoted in four or more decimal places. Indeed, divisibility is a necessary characteristic of a currency to accommodate the valuation for all types and sizes of transactions.

On the other hand, the price differences in the magnitude of several decimal places e. For comparison most world currencies use no more than two decimal points for price quotations Yermack We may conclude that, generally, due to almost infinite divisibility possibilities of BitCoin its use and popularity may grow compared to standard currencies, although small price denominations may reduce ability of consumers to accurately distinguish relative prices Table 2.

BitCoin prices show extremely high short-run volatility, which diminishes its ability in representing an effective unit of account Yermack The frequent BitCoin price changes cause direct and indirect costs to businesses and consumers. Businesses that use BitCoin have to adjust prices frequently, otherwise they may realize decrease in returns because of underpriced goods and services or loss of competitiveness because of overpriced goods and services.

This is particularly problematic for businesses trading outputs in BitCoins, while paying for production factors and intermediate inputs in local standard currency e. US dollar, Euro, Yen, British Pound , causing discrepancy in relative prices between outputs and inputs in presence of high BitCoin price volatility. Frequent price changes in turn become confusing to consumers, as it becomes more difficult to spot the true relative prices of goods and services.

Footnote 6. Although, high price volatility of BitCoin may inflict risk to its holders, entrepreneurial innovations provide alternative solutions which diminish the price volatility risk. For example, market exchange pricing may facilitate price setting to businesses retailers and widen spending options to consumers. The market exchange pricing enable retailers to set prices in one currency e.

US dollar, Euro, Yen, British Pound while displaying them to consumers simultaneously and automatically updated in more currencies, including in BitCoin, reflecting the current market exchange rates. This system makes relatively costless price tracking in BitCoin to businesses that reflect up-to-date market exchange rate particularly for online sales.

Another example includes instantaneous exchange facilities which enable retailers to accept BitCoin as payment without actually receiving BitCoins. This system involves a third party which intermediates the exchange of BitCoins, paid by consumers, to standard currency, which is received by the retailer e.

Because sellers never actually receive BitCoins, they avoid the BitCoins exchange risk; the exchange risk is beard by the intermediaries which receive a fee in return Luther and White In the context of BitCoin use as a unit of account, the extremely high price volatility reduces BitCoin power to convey accurately the relative prices of goods and services in the economy Table 2. If, as argued by Luther and White , financial developments are providing alleviating options for addressing the issue of BitCoin price volatility, then the adverse impacts of price volatility may decline in future.

The value of the money must remain stable over time to allow their use in exchanges in different points of time. We identify two features of BitCoin as store of value, which differ substantially from traditional currencies: non-inflationary supply and cyber security see Table 2 for summary.

Standard currencies are usually inflationary, meaning that their value reduces over time and thus diminishes the ability of the currency to function as a store of value. In contrast, an important advantage of BitCoin is the protection against inflation as a safe haven from government interference. Given that under the current mechanism the future number of BitCoins is capped to a maximum amount of 21 million units with no expansion possible beyond this amount, BitCoin will be exposed to deflationary pressures if its use as an investment alternative or for use as a medium of exchange increases.

Footnote 7 On the one hand, this is beneficial to BitCoin holders, as it will make them richer over time. On the other hand, the expectation of higher future value of BitCoins may lead to its hoarding in anticipation of higher price which in turn may reduce its use in exchanges of goods and services. Meiklejohn et al. We may conclude that, in the absence of inflationary pressures, BitCoin popularity should increase compared to standard currencies, although deflationary pressure may act as a countervailing force Table 2.

One of the main threats to BitCoin ability to preserve its value to the holders is the issue of cyber security. In the past, many BitCoin owners have lost their virtual money through online theft. Standard currencies give a possibility to protect it against theft either by physically hiding it e. BitCoin is a virtual currency and thus it cannot be physically hidden.

BitCoins must be held in computer accounts known as virtual wallets. The security of BitCoin wallets has often been a major problem. Even BitCoin exchanges were subject to cyber-attacks and thefts as they are common target of hackers. In the context of BitCoin use as a store of value, BitCoin sensitivity to cyber-attacks and thefts reduces trust in BitCoin as a currency and hence impedes its growth and chances of becoming a global currency Table 2.

Among all BitCoin features identified and discussed above, eventually, price volatility is the one with the largest differences compared to the major world currencies, such as US dollar, Euro, Yen, British Pound. One consequence of such extreme price volatility is that BitCoin may not succeed as a global currency to be accepted by suppliers and consumers, as it may fail to accurately convey relative prices of goods and services in the economy and may generate uncertainties to its holders due to its inability to preserve stable value over time.

Given that BitCoin is a relatively new currency, its price formation is not well understood yet. In order to better understand reasons for such extremely high price volatility, in this section we attempt to identify the drivers of BitCoin price and estimate their relative importance econometrically. The existing studies in the literature e. According to Buchholz et al. According to the quantity theory of money, the BitCoin supply is determined by the total stock of BitCoin in circulation.

The BitCoin demand is represented by the size of BitCoin economy i. The BitCoin velocity measures the frequency at which one unit of BitCoin is used for purchase of goods and services. The quantity theory implies that the price of BitCoin decreases with the velocity and the stock of BitCoins, but increases with the size of BitCoin economy and the general price level.

The demand for BitCoin is primarily driven by its value as a medium of exchange. BitCoin does not have intrinsic value like commodity currency such as gold standard. For example, the key difference between the gold standard and BitCoin is that the demand for BitCoin is driven solely by its value in future exchange, whereas the demand for commodity currency is driven by both its intrinsic value and its value in future exchange. The BitCoin supply is given by the total stock of units put in circulation, which is publicly known and is fixed in the long-run.

Whereas BitCoin supply is exogenous, the supply of gold is endogenous, as it responds to changes in production technology e. Given the exogeneity of BitCoin supply, the primary driver of its price developments is expected to be the demand side shocks. By altering expectations of future use in exchanges, such shocks to demand have the potential to produce large swings in the BitCoin price Luther and White There are several BitCoin-specific factors which, in addition to traditional currency price determinants, such as market supply and demand, determine its demand.

This is partially linked to the fact that BitCoin has been created relatively recently and to the nature of the currency. Barber et al. First, BitCoin price may be affected by the risk and uncertainty of the whole BitCoin system. Given that BitCoin is a fiat currency and thus intrinsically worthless, it does not have an underlying value derived from consumption or its use in production process such as gold.

The value of a fiat currency is based on trust that it will be valuable and accepted as a medium of exchange also in future Greco ; Kovenock and Vries Footnote 8 The expectations about trust and acceptance are particularly relevant for BitCoin which, being a relatively new currency, is in the phase of establishing its market share by building credibility among market participants.

Second, being a virtual currency, BitCoin is more vulnerable to cyber-attacks than traditional currencies, which can destabilize the whole BitCoin system and eventually lead to a collapse of BitCoin. Such attacks have been frequently occurring in the BitCoin system in the past Barber et al. Third, BitCoin price may be affected by its attractiveness as an investment opportunity for potential investors.

According to Gervais et al. The role of information is particularly important in the presence of many alternative investment choices and positive search costs. Given that investment demand depends on the costs associated with searching for information for potential investment opportunities available on the market, such as, the stock exchange, those investment opportunities which are under a particular attention of news media may be preferred by potential investors, because they reduce search costs.

In turn, increased investment demand for BitCoin may exercise upward pressure on BitCoin price. Indeed, Lee finds such evidence for BitCoin, whereby the alteration of positive and negative news generated high price cycles. This implies that the attention-driven investment behavior can affect BitCoin price either positively or negatively, depending on the type of news that dominate in the media at a given point of time.

Van Wijk stresses the role of global macroeconomic and financial development, captured by variables such as stock exchange indices, exchange rates, and oil prices measures in determining BitCoin price. The impact of macroeconomic and financial indicators on BitCoin price may work through several channels. For example, stock exchange indices may reflect general macroeconomic and financial developments of the global economy.

Favorable macroeconomic and financial developments may stimulate the use of BitCoin in trade and exchanges and thus strengthen its demand, which may have positive impact on BitCoin price. Inflation and price indices are other type of indicators capturing important macroeconomic and financial developments. According to Krugman and Obstfeld and Palombizio and Morris , oil price is one of the main sources of demand and cost pressures, and it provides an early indication of inflation development.

Thus, when the price of oil signals potential changes in the general price level, this may lead to depreciation or appreciation of BitCoin price. Also the exchange rate may reflect inflation development and thus impact positively BitCoin price as indicated above. A decline in the stock prices induces foreign investors to sell the financial assets they hold. This leads to a depreciation of the underlying currency, but may stimulate BitCoin price, if investors substitute investment in stocks for investment in BitCoin.

Hence, in this case the stock exchange indices are expected to be positively related to BitCoin price. To account for the three drivers identified in the previous section, we specify the following BitCoin price equation:. US dollar per unit of BitCoin , p t is the general price level of goods and services in the economy e. The first four variables p t , y t , v t , and b t account for demand and supply drivers of BitCoin price driver 1.

Variable a t captures the BitCoin attractiveness driver 2. Finally, variable m t represents global macroeconomic and financial developments driver 3. The econometric model 1 contains mutually interdependent variables—BitCoin price and its explanatory variables. According to Engle and Granger , regressions of interdependent and non-stationary time series may lead to spurious results. In order to avoid spurious regression, it is important to test the properties of the time series involved.

Therefore, in the first step, the stationarity of time series is determined, for which we use two unit root tests: the augmented Dickey—Fuller ADF test and the Phillips—Perron PP test. If two individual time series are non-stationary, their combination may be stationary Engle and Granger In this special case, the time series are considered to be cointegrated, implying that there exists a long-run equilibrium relationship between them.

The number of cointegrating vectors is determined by the maximum eigenvalue test and the trace test. Both tests use eigenvalues to compute the associated test statistics. We follow the Pantula principle Pantula to determine whether a time trend and a constant term should be included in the model. It includes an error correction term indicating the speed of adjustment of any disequilibrium towards a long-term equilibrium state.

In other words, the error correction term captures the changes in the BitCoin price required to eliminate the past deviation of the prices from the equilibrium levels. As usual, in order to ensure the adequacy of the estimated models, we implement a series of specification tests: Lagrange-multiplier LM test for autocorrelation in the residuals; Jarque—Bera test to check if the residuals in the Vector-Error Correction VEC are normally distributed and a test of stability of the model.

We use the historical number of total BitCoins number of BitCoins which have been mined to account for the total stock of BitCoins in circulation, b t. We use two alternative proxies for the size of BitCoin economy, y t : the total number of unique BitCoin transactions per day number of transactions , and the number of unique BitCoin addresses used per day number of addresses.

Following Matonis , we proxy the monetary velocity of BitCoin circulation, v t , by BitCoin days destroyed for any given transaction days destroyed. This variable is calculated by taking the number of BitCoins in transaction and multiplying it by the number of days since those coins were last spent. All these data are extracted from quandl. To measure the price level of global economy, p t , we use exchange rate between the US dollar and the Euro exchange rate extracted from the European Central Bank.

For example, if the US dollar would appreciate against the Euro, most likely it will also appreciate against the BitCoin. Consequently, an increase in the exchange rate between the Euro and the US dollar would lead to a decrease in the amount of US dollar that have to be paid for one BitCoin, which decreases its price. In order to capture BitCoin attractiveness, a t , we follow Kristoufek and use the volume of daily BitCoin views on Wikipedia views on Wikipedia.

In addition, we also construct a variable capturing the number of new members new members and new posts on online BitCoin forums new posts extracted from bitcointalk. As explained above, the variable new members captures the size of the BitCoin economy but also attention-driven investment behavior of new BitCoin members.

To account for global macroeconomic and financial developments, m t , we follow van Wijk and use oil price oil price and the Dow Jones stock market index Dow Jones. Following the drivers of BitCoin price formation identified in Sect. The differences in the specifications between the estimated models are summarized in Table 3.

Models 1. Model 2. Model 3. Models 4. The estimation results are reported in Tables 4 , 5 , 6 and 7. Tables 4 and 5 report the short-run impact of different determinants on BitCoin price. The short-run effects represent short-run dynamics of variables in the cointegrated system. They describe how the time series react when the long-run equilibrium is distorted. According to the results reported in Tables 4 and 5 , a number of variables have statistically significant short-run effect on BitCoin price adjustments.

In particular, this is the case for own price effects, the stock of total BitCoins number of BitCoins BitCoin days destroyed days destroyed and Wikipedia views views on Wikipedia. Tables 6 and 7 show the long-run impacts of different determinants on BitCoin price. According to the results reported in Tables 5 and 6 , the long-run relationship between BitCoin price and the explanatory variables considered in the estimated models is stronger than the short-run impact.

In the following we discuss the long-run results with respect to the three drivers of BitCoin price formation. In the end, if you look at the wealth of people- rich people hold a lot of land and stocks and gold. In a country like the US, the top 1 percent of people own percent of the top assets. Early "miners" were able to buy into the alternative currency cheap, because when bitcoins first debuted they sold for mere dollars. Prices have soared and subsequently sunk into the hundreds from thousands.
