Face-to-Face Transactions: In some cases, you can also meet up with a person directly and purchase Bitcoins with them at a predetermined rate. Websites such as localbitcoins help you find traders who are willing to offer such deals. However, one needs to be careful while making such transactions as there have been many scams in the past. No, all cryptocurrencies do not have their individual blockchains. There are many cryptocurrencies which are modelled on other cryptocurrencies - the most popular example of this is how many cryptocurrencies start off using the Ethereum blockchain as a base model and are basically ERC tokens before they move to their own blockchain.
While cryptocurrencies definitely function on a blockchain system and cannot exist without it, it is not a compulsion for them to have their own, unique blockchain network. EOS and TRX are two of the best examples of cryptocurrencies which existed on the Ethereum blockchain network for about a year after their launch - but have now moved on to their own blockchains.
Currencies move away from the base blockchain to their own blockchain when the developers believe that the currency has matured and needs to expand its operations. However, it is not a compulsion for each cryptocurrency to have its own blockchain. Cryptocurrencies, unlike fiat currencies, are not backed by any government or a single organization.
Yet they carry a value - which increases or decreases from time to time. There are a number of reasons as to why a cryptocurrency carries value:. Demand and Supply: The primary reason why anything has value is because of the basic economic concepts of demand and supply.
The supply of most cryptocurrencies is fixed. However, the demand is high. If investors stop investing in the cryptocurrency and no one is willing to buy them , the price will begin to fall. However, once people begin to buy cryptocurrencies - the price starts to rise. Need: Every cryptocurrency has something unique to offer. Each cryptocurrency solves a unique need.
The stronger the need for the currency, the higher its demand. And the higher the demand, the higher the price. Use Case: While each cryptocurrency caters to a different need, not every cryptocurrency can practically be used. In order for a cryptocurrency to gain demand - and therefore gain price, it needs to have a strong use case in real life. The more practically usable the currency is, the higher are the chances that the demand will be stronger.
Energy Intensive Process: Cryptocurrencies are generated as well as transactions are verified with the help of a process known as cryptocurrency mining. Considering that mining is an energy intensive activity, miners do this expecting something in return. That comes to them as block rewards - basically a number of cryptocurrencies which they get in exchange for spending their energy and money on mining.
Block rewards reduce every few years - however in that time, the price of currency grows to even out the reduction of rewards. While it is not practical to point out the fastest cryptocurrency in terms of transaction time, Ripple is generally considered to be one of the fastest few cryptocurrencies.
However, when it comes to transaction time, cryptocurrencies can make transactions based on the blockchain network that they are based on. If there is congestion on the blockchain - it would take a longer time to transact. Big names such as Ethereum and Bitcoin are usually slower because of the massive load on their blockchain.
However, considering the load and the need of the users, both these top names are now working towards improving their existing framework. For Bitcoin, improvements such as the lightning network and the segregated witnesses setup is all set to bring in major changes. In case of Ethereum, the developers are working towards newer protocols and second layer scaling solutions - which will help the blockchain improve on its currency transaction time.
Before creating your own cryptocurrency, you need to first define a purpose that it stands for. Does your currency cater to a specific need that the people are facing? Does it have a practical use-case is the first and the most basic of questions that needs to be answered.
Following that, a team of developers and legal experts needs to be set up who can define the various technical and legal aspects of this cryptocurrency. One also needs to consider the platform upon which this currency has to be built. Initially, most cryptocurrencies launch as tokens on other blockchain platforms such as ERC tokens on Ethereum blockchain.
However, as the project matures, it moves on to its own, individual blockchain. Post the ideation, a whitepaper needs to be written up - this whitepaper contains all the technical, financial as well as legal details about the cryptocurrency. The proposal is then sent to the governing body such as the Securities and Exchanges Commission which takes a look at the upcoming offering and determines its status as a security.
Once the code is ready and the preparation has been done by the developers and all the permissions have been taken from the legal and financial watchdog bodies - an ICO Initial Coin Offering can be launched. For those who may be unaware, an Initial Coin Offering is basically a fundraising process where anyone can invest cryptocurrencies in your project.
If the idea behind your currency is appealing and many people can relate to it, they will invest in your currency by providing you cryptocurrencies in exchange for your token. As the value of your token grows, the profits of the investors would increase and hence they invest.
Basically, starting off a cryptocurrency is like starting off with a start-up business. Companies create their own cryptocurrencies for multiple reasons. However, it all boils down to one word - profit. When they create their own cryptocurrencies, users would need to buy that currency when they want to transact over that specific platform. This would ensure that the demand for the platform specific currency is steady as long as people want to buy stuff from the platform - hence keeping the price steady.
Moreover, these platform-specific cryptocurrencies can later be traded by the company for other cryptocurrencies and can be encashed for even more profits. This is the basic reason as to why companies create their own cryptocurrencies. The answer to this is quite simple. When the price hits rock-bottom.
However, market cap is the biggest indicator of the faith that people are showing in a currency. Governments cannot ban cryptocurrencies. They are created in such a manner that it is practically impossible to ban cryptocurrencies. However, the government can order banks to ban accounts which trade in cryptocurrencies and can instruct cryptocurrency businesses to shut down - thereby choking the crypto-industry.
Cryptocurrencies are changing the way we know the modern day economic systems to be. It is becoming a common, everyday conversation and is constantly being covered by the mainstream news of late. It is important to stay abreast with this technology which is likely to change the future of finance as we know it to be!

They are permanently based on the blockchain. Hence, when someone says they own X amount of coins, what they really mean is that their password can legitimately claim X amount of coins on the blockchain. Cryptocurrency private key concept Getty Images. These private keys are what crypto holders store on their wallets, which, as you must have guessed, are special kinds of software or devices designed specifically for this purpose. In instances where a crypto holder loses access to his or her private key , the cryptocurrencies associated with such keys could be lost permanently.
With the help of a cryptographic technique, private keys are encrypted to create wallet addresses, which can be likened to bank account numbers. In essence, you need your private key to digitally sign transactions. A blockchain is exactly what it sounds like — a virtual chain of blocks each containing a batch of transactions and other data. Once each block is added to the chain, it becomes immutable, meaning the data stored inside it cannot be changed or removed.
The nodes perform a variety of roles on the network, from storing a full archive of all historical transactions to validating new transaction data. By having a distributed group of people all maintaining their own copy of the ledger, blockchain technology has the following advantages over traditional finance where a master copy is maintained by a single institution:.
Think of it as having a cluster of computers take up the roles of a bank by consistently updating the balance sheets of users. Instead, there are multiple copies of the balance sheets distributed across several computers, with each node, or computer connected to the network, functioning as a separate server.
This infrastructural design makes it possible for cryptocurrencies to evade the security mishaps that often plague fiat. Depending on how big the network is, it can be prohibitively expensive to carry out a coordinated attack. Also, it is worth mentioning that the distributed nature of these digital assets establishes their censorship-resistant attributes.
Unlike the case with banks, which governments regulate, cryptocurrencies have their databases spread across the globe. Therefore, when a government shuts down one of these computers or all the computers within its jurisdiction, the network will continue to function because there are potentially thousands of other nodes in other countries beyond the reach of one government.
Crowd of people on network connection lines. Getty Images. So far in this guide, we have explained why cryptocurrencies are secure and why they are censorship-resistant. Now, let us take a look at how crypto transactions are vetted. Recall that blockchains are distributed databases where all the transactions executed on a crypto network are recorded permanently.
Every block of transactions is linked together chronologically in the order the transactions were validated. Because it is impossible to set up a central authority or bank to manage blockchains, crypto transactions are validated by nodes computers connected to a blockchain.
So the question is: How do these networks ensure that node operators are willing to partake in the validation process? With incentives, validators are encouraged to participate actively and honestly in the validation process to earn rewards in the form of newly minted created cryptocurrencies. This incentive system sets the rules that govern the process of picking validators who would, in turn, verify the next batch of transactions.
It also ensures that the activities of the validators align with the goal of the network as a whole. Validator nodes found to be involved in actions that undermine the validity of the crypto network can be barred from taking part in subsequent validation processes or punished accordingly. These incentive infrastructures are also known as consensus protocols. There is a wide range of consensus protocols being used by existing blockchain networks. The two most common ones are:.
Tokens are digital assets issued by decentralized applications based on blockchains. These are applications similar to the ones you might find on your smartphone, but instead of being operated by a single company, they run completely autonomously. Think of it like a free Uber app where taxi drivers and customers can connect together without having to pay the middleman company a cut of profits.
Because these applications depend on the infrastructure of blockchains, transactions involving tokens come with an added fee settled in the native cryptocurrency of the blockchain in question. The value of a cryptocurrency usually depends on the utility of its underlying blockchain — though there have been many instances where social media hype and other superficial factors have played a role in pumping up prices.
It all boils down, though, to the demand for the coin relative to its supply and whether the buyer is willing to pay more than the amount the seller initially acquired the coin for. Notably, cryptocurrencies tend to favor a deflationary system, whereby the number of new coins introduced to the market is predictable and gradually reduces over time.
For many cryptocurrencies, another important element is the total number of coins that can ever exist is often fixed. For instance, there will be only 21 million bitcoins created, of which more than 18 million are already in circulation. This deflationary-based system is the complete opposite of what we have in traditional finance, where governments have the license to print an infinite number of fiat notes and inadvertently devalue their currencies.
Bitcoin was the first of the many cryptocurrencies that exist today. Following its introduction in , developers began to create other variants of cryptocurrencies based on the technology powering the Bitcoin network. In most cases, the cryptocurrencies were designed to improve upon the standards set by Bitcoin. Initially, cryptocurrency was pushed as an alternative to fiat currency based on the premise that it is portable, censorship-resistant, available globally and an affordable means of executing cross-border transactions.
As a result, most crypto holders have shifted their attention to the investment potential of cryptocurrencies, which has since birthed the speculative side of the crypto market. Investors seem to be more concerned about the possibility that the price of a cryptocurrency may rise sometime in the future than whether they can use cryptocurrencies to purchase goods and services, and so crypto is now predominantly viewed as an investment.
