The list of merchants accepting Bitcoin continues to expand, including merchants as diverse as Microsoft, Expedia, and Subway, the sandwich chain. Although Bitcoin is widely recognized as pioneering, it is not without limitations. For example, it can only process seven transactions a second. By contrast, Visa handles thousands of transactions per second. The time it takes to confirm transactions has also risen.
Not only is Bitcoin slower than some of its alternatives, but its functionality is also limited. Other currencies like Bitcoin include Litecoin , Zcash and Dash , which claim to provide greater anonymity. Ether and currencies based on the Ethereum blockchain have become increasingly popular.
However, issues with Ethereum technology have since caused declines in value. Ethereum has seen its share of volatility. Put simply, smart contracts are computer programs that can automatically execute the terms of a contract.
With traditional operations, numerous contracts would be involved just to manufacture a single console, with each party retaining their own paper copies. However, combined with blockchain, smart contracts provide automated accountability. Smart contracts can be leveraged in a few ways: When a truck picks up the manufactured consoles from the factory, the shipping company scans the boxes. Beyond payments, a given worker in production could scan their ID card, which is then verified by third-party sources to ensure that they do not violate labor policies.
As mentioned previously, cryptocurrency has no intrinsic value—so why all the fuss? People invest in cryptocurrencies for a couple primary reasons. Apart from pure speculation, many invest in cryptocurrencies as a geopolitical hedge. During times of political uncertainty, the price of Bitcoin tends to increase. Bitcoin is not the only cryptocurrency with limits on issuance.
The supply of Litecoin will be capped at 84 million units. The purpose of the limit is to provide increased transparency in the money supply, in contrast to government-backed currencies. With the major currencies being created on open source codes, any given individual can determine the supply of the currency and make a judgment about its value accordingly. Applications of the Cryptocurrency. Cryptocurrencies require a use case to have any value. The same dynamic applies to cryptocurrencies. Bitcoin has value as a means of exchange; alternate cryptocurrencies can either improve on the Bitcoin model, or have another usage that creates value, such as Ether.
As uses for cryptocurrencies increase, corresponding demand and value also increase. Regulatory Changes. Because the regulation of cryptocurrencies has yet to be determined, value is strongly influenced by expectations of future regulation. In an extreme case, for example, the United States government could prohibit citizens from holding cryptocurrencies, much as the ownership of gold in the US was outlawed in the s.
Technology Changes. Unlike physical commodities, changes in technology affect cryptocurrency prices. July and August saw the price of Bitcoin negatively impacted by controversy about altering the underlying technology to improve transaction times. Conversely, news reports of hacking often lead to price decreases. Still, given the volatility of this emerging phenomenon, there is a risk of a crash.
Many experts have noted that in the event of a cryptocurrency market collapse, that retail investors would suffer the most. Initial coin offerings ICOs are the hot new phenomenon in the cryptocurrency investing space. ICOs help firms raise cash for the development of new blockchain and cryptocurrency technologies. Startups are able to raise money without diluting from private investors or venture capitalists.
Bankers are increasingly abandoning their lucrative positions for their slice of the ICO pie. Not convinced of the craze? With cryptocurrencies still in the early innings, there are many issues surrounding its development.
According to this theory, members of society implicitly agree to cede some of their freedoms to the government in exchange for order, stability, and the protection of their other rights. By creating a decentralized form of wealth, cryptocurrencies are governed by code alone. The following section will discuss these tangible aspects of cryptocurrency development. Under current accounting guidelines, cryptocurrencies are most likely not cash or cash equivalents since they lack the liquidity of cash and the stable value of cash equivalents.
In the US, IRS Revenue Ruling stated that holders of cryptocurrencies should account for them as personal property, with gains or losses on purchases or sales. The value of cryptocurrency holdings on balance sheets would be at cost or fair market value at the time of receipt. The ruling left many questions unanswered. These rules exclude certain investment assets, but do not explicitly exclude cryptocurrencies, so their applicability is unclear.
Outside the US, accounting treatment of cryptocurrencies varies. In the EU, a decision of the European Court of Justice rules that cryptocurrencies should be treated like government-backed currencies, and that holders should not be taxed on purchases or sales. Regulatory treatment of cryptocurrencies continues to evolve, but because the technology transcends global boundaries, the influence of national regulators is limited.
Japan has not only legally recognized Bitcoin, but also created a regulatory framework to help the industry flourish. This is considered a major step forward for legitimizing cryptocurrencies. The media has generally praised the new regulatory scheme, though the Japanese Bitcoin community has criticized the system as hampering innovation.
The move follows the major fraud and investor losses from the Mt. Gox Bitcoin exchange scandal. The retail investor— Mrs. She wants something regulated and trustworthy. On the other hand, US regulators have been less than keen about the rise of virtual currencies. US regulators are starting to crack down on previously unregulated cryptocurrency activities. Take initial coin offerings ICOs for example. Despite their popularity, many ICOs are for new cryptocurrencies with speculative business models, and have been widely criticized as scams.
Since ICOs can be sold across national borders, it remains to be seen whether ICO issuers will choose to comply or simply move transactions outside of the US. Due to the pseudonymous nature of ICO transactions, it may be difficult for national governments to significantly limit cryptocurrency sales or trading. Regulation is also expanding beyond ICOs.
This move is a result of concern that cryptocurrency investors believe they are receiving the protections and benefits of a registered exchange when they, in fact, are not. To date, compared to securities brokers, cryptocurrency exchanges have had no capital rules and have been largely unregulated other than for anti-money laundering—something that seems to be subject to change.
Exchanges registered with the SEC will be subject to inspections, required to police their markets, and mandated to follow rules aimed at ensuring fair trading. New York State created the BitLicense system , which imposes new requirements on companies looking to conduct business with New York residents. As of mid, only three BitLicenses have been issued, and a far greater number withdrawn or denied.
In contrast, Vermont and Arizona have embraced the new technology. Both states passed laws providing legal standing to facts or records tied to a Blockchain, including smart contracts. Arizona also passed a second law prohibiting blockchain technology from being used to track the location or control of a firearm.
Computer hacking and theft continue to be impediments to widespread acceptance. These issues have continued to rise in tandem with the popularity of cryptocurrencies. In July , one of the five largest Bitcoin and Ethereum exchanges Bithumb was hacked, resulting in the theft of user information as well as hundreds of millions of Korean Won.
The pseudonymous nature of blockchain and Bitcoin transactions also raises other concerns. In a typical centralized transaction, if the good or service is defective, the transaction can be cancelled and the funds returned to the buyer. Despite advancements since their inception, cryptocurrencies rouse both ire and admiration from the public. The challenge proponents must solve for is advancing the technology to its full potential while building the public confidence necessary for mainstream adoption.
After all, critics are not entirely wrong. Bitcoin and its investors could end up like brick and mortar stores, eclipsed by the next big thing. New cryptocurrency advancements are often accompanied by a slew of risks: theft of cryptocurrency wallets is on the rise, and fraud continues to cast an ominous shadow on the industry.
Still, cryptocurrencies and blockchain could be truly transformative. The only limit is your imagination. Cryptocurrencies are primarily used to buy and sell goods and services, though some newer cryptocurrencies also function to provide a set of rules or obligations for its holders. During mining, two things occur: Cryptocurrency transactions are verified and new units are created. Effective mining requires powerful hardware and software.
Miners often join pools to increase collective computing power, splitting profits between participants. Groups of miners compete to verify transactions. A cryptocurrency is a digital currency, which is an alternative form of payment created using encryption algorithms.
The use of encryption technologies means that cryptocurrencies function both as a currency and as a virtual accounting system. To use cryptocurrencies, you need a cryptocurrency wallet. These wallets can be software that is a cloud-based service or is stored on your computer or on your mobile device.
The wallets are the tool through which you store your encryption keys that confirm your identity and link to your cryptocurrency. What are the risks to using cryptocurrency? Cryptocurrencies are still relatively new, and the market for these digital currencies is very volatile. Since cryptocurrencies don't need banks or any other third party to regulate them; they tend to be uninsured and are hard to convert into a form of tangible currency such as US dollars or euros.
In addition, since cryptocurrencies are technology-based intangible assets, they can be hacked like any other intangible technology asset. Finally, since you store your cryptocurrencies in a digital wallet, if you lose your wallet or access to it or to wallet backups , you have lost your entire cryptocurrency investment. Look before you leap! Before investing in a cryptocurrency, be sure you understand how it works, where it can be used, and how to exchange it. Read the webpages for the currency itself such as Ethereum , Bitcoin or Litecoin so that you fully understand how it works, and read independent articles on the cryptocurrencies you are considering as well.
Use a trustworthy wallet.
And there are a lot of people who think this model is the future of all software, the thing that will finally challenge the FANG stocks and venture capital to boot. It's not at all clear yet that decentralized applications are actually useful to most people relative to traditional software. Simply put, you cannot argue that for everyone Bitcoin is better than PayPal or Chase. Or that for everyone Filecoin is better than Dropbox or iCloud. In fact, on almost every dimension, decentralized services are worse than their centralized counterparts:.
And no, this isn't just because they are new. This won't fundamentally change with bigger blocks, lightning networks, sharding, forks, self-amending ledgers, or any other technical solutions. That's because there are structural trade-offs that result directly from the primary design goal of these services, beneath which all other goals must be subordinated in order for them to be relevant: decentralization.
Remember that "elaborate and expensive competition" I described? Well, it comes at the cost of throughput. Remember how users need to "cryptographically sign" their transaction announcements? Well, those private keys need to be held onto much more securely than a typical password passwords can be recovered. Remember how "no single entity operates" these networks? The flip side is that there is no good way to make decisions or govern them.
Sure, you can make decentralized applications more efficient and user friendly by, for example, centralizing users' cryptographic signing keys i. But then we're mostly back to square one and would be better off using a service that is centralized. Thus, bitcoin, for example, isn't best described as "Decentralized PayPal. Bottom line: centralized applications beat the pants off decentralized applications on virtually every dimension. And not only are decentralized applications better at this one thing, they are the only way we can achieve it.
Censorship resistance means that access to decentralized applications is open and unfettered. Transactions on these services are unstoppable. More concretely, nothing can stop me from sending Bitcoin to anyone I please. Nothing can stop me from executing code on Ethereum. Nothing can stop me from storing files on Filecoin. As long as I have an internet connection and pay the network's transaction fee, denominated in its crypto asset, I am free to do what I want. If Bitcoin is capitalism distilled, it's also a kind of freedom distilled.
Which is why libertarians can get a bit obsessed. And for readers who are crypto enthusiasts and don't want to take my word for it, will you at least listen to Adam Back and Charlie Lee? So while we can't say "for everyone Bitcoin is better than Visa," it is possible that for some cohort of users Bitcoin truly is the only way to make a payment.
Who needs censorship resistance so much that they are willing to trade away the speed, cost, scalability, and experience benefits of centralized services? I am saying that in order for decentralized applications themselves to have utility to some cohort, that cohort must be optimizing for censorship resistance.
While there is not a lot of good data, actual users of decentralized applications seem to fall into two categories:. So far, most decentralized applications have very little use relative to traditional services. Bitcoin, for example, has fewer mainstream merchants accepting it as a payment option in the U.
And for all the talk of Bitcoin's value as a payments system in developing countries or emerging markets like China, it is traditional software i. At the same time, use of Bitcoin on the dark web and for ransomware is evident, even if it is hard to get good data. But aren't people using Bitcoin as a "store of value?
But remember I'm not talking about investing in the crypto asset yet. I'm talking about whether there are people who find a decentralized application for payments which is enabled by that asset useful. Real estate is only a good store of value in the long run if people live and work in the buildings.
The same is true of decentralized applications. What should we make of Ethereum evaluated through the "censorship resistance" lens? After all, it seems to be getting a ton of use by developers. Since Ethereum is a developer platform for decentralized applications , does that mean it is developers who have been censored or blocked somehow?
In a way, yes. Developers and start-ups who wish to build financial products do not have open and unfettered access to the world's financial infrastructure. While Ethereum doesn't provide access to that infrastructure, it does provide a different infrastructure that can be used to, for example, create and execute a financial contract. Since Ethereum is a platform, its value is ultimately a function of the value of the applications built on top.
In other words, we can ask if Ethereum is useful by simply asking if anything that has been built on Ethereum is useful. For example, do we need censorship resistant prediction markets? Censorship resistant meme playing cards? Censorship resistant versions of YouTube or Twitter?
Even in year 1 of the web we had chat rooms, email, cat photos, and sports scores. What are the equivalent killer applications on Ethereum today? Given how different they are from the app models we know and love, will anyone ever really use decentralized applications?
Will they become a critical part of the economy? It's hard to predict because it depends in part on the technology's evolution but far more on society's reaction to it. For example: until relatively recently, encrypted messaging was only used by hackers, spies, and paranoids. That didn't seem to be changing. Until it did. WhatsApp is end-to-end encrypted.
The press solicit tips through SecureDrop. Yes, the technology got a little better and easier to use. But it is mainly changes in society that are driving adoption. In other words, we grew up in the rainforest, but sometimes things change and it helps to know how to adapt to other environments. And this is the basic argument that the smart money is making on crypto assets and decentralized applications: that it's simply too early to say anything. That it is a profound change. That, should one or more of these decentralized applications actually become an integral part of the world, their underlying crypto assets will be extremely valuable.
So might as well start placing bets now and see how it goes. Don't get to hung up on whether we see the killer apps yet. I would summarize the argument as: in the long-run, a crypto asset's value is driven by use of the decentralized application it enables. While it's early, the high valuations are justified because even if the probability of mass adoption is small, the impact would be very large, so might as well go along for the ride and see what happens.
Bitcoin is up 5x in a year, Ethereum is up 30x. To understand what's going on, let's look at the buyer and seller mentality right now, starting with the buyers. If you invested early in Bitcoin or Ethereum, you are sitting on a windfall.
It feels like you are playing with "house money," a well-known psychological effect. You feel smart and willing to risk more than you otherwise would if it was "your money. If you didn't invest, the fear-of-missing-out continues to build until the "screw it" moment when you buy in. Maybe you read about Bitcoin, didn't understand it, and followed Warren Buffet's good advice not to invest in things you don't understand.
Some of your friends made money but you still ignored it. Then you read about Ethereum, which you really didn't understand, also passed on buying, and later found out that your friends are planning to retire because they did. The lesson seems to be anti-Buffet : only invest in things you don't understand. This is causing people to check their judgement at the door when the latest all-time high finally convinces them to jump into the market. Because there will be sellers to fill the demand, especially the demand coming from people who have decided they will never understand this stuff so will just place bets on things that sound complex and impressive.
Let's think about these sellers. And by sellers, I don't mean people selling their holdings of existing crypto assets. I mean new issuers. Teams launching new crypto assets. The basic model is to pre-sell some percentage of the crypto assets the proposed network will generate as a way to fund the development of the decentralized application before it launches. The project founders tend to hold on to some percentage of these assets.
Which means that raising money for a project this way is a non-dilutive as it is not equity and b not debt, so you never have to pay anyone back. This is basically free money. It's never been this good for entrepreneurs, even in the 90s dot-com boom. Which makes it incredibly tempting to try and shoe-horn every project that could perhaps justify an "initial coin offering" to go for it, even if they aren't actually building a decentralized application.
After all, an ICO lets you exit before you even launch. And there is a pervasive narrative out there that supports entrepreneurs looking to create new crypto assets. The idea is that by selling assets to users before your network launches, you create "evangelists" who will be early users and promoters you wouldn't otherwise have if there were no financial incentive to participate in your community. The problem with this line of thinking is that it conflates early investors with early users.
The overlap between people who buy your crypto asset and people who actually want to use the service you are building is likely very, very small, especially during market manias like this one. It creates a false sense of "product-market fit. But that's because the "market" are people who want to get rich and the "product" you are selling is a "way to get rich.
Consider the following. The total market cap of crypto assets has been increasing by an order of magnitude every few years. Where will they be in ? It's certain that many most? Though an important alt coin from did stick around and drove the most recent boom to new heights by being the platform to power all the others: Ethereum.
