Cryptocurrency is the new thing that everyone is talking about: Bitcoin, Ethereum, Litecoin, etc. But what is it? What should you know about it?
What Cryptocurrency Is
Cryptocurrency is a form of digital money. It can only be used in transactions or exchanged for other currencies. It’s not a country’s currency (like the US dollar); it doesn’t have any government backing; and it isn’t backed by gold or silver either. It’s not “backed” by anything. The value of cryptocurrencies fluctuates wildly, which can make them risky to use.
All cryptocurrency is created by computers “mining.” These computers solve complex mathematical problems to create new coins. That’s where the name comes from: Cryptography is the practice of solving cryptographic problems. But cryptocurrency isn’t just used for cryptography – it’s also used to store and exchange other kinds of information, like files and messages.
The History of Cryptocurrency
Bitcoin was first created in 2009 – but only very recently has it become popular enough that governments are taking notice. China banned cryptocurrency exchanges in September 2017, claiming they were illegal financial activity that threatened people’s deposits and privacy; other countries are looking into banning cryptocurrency altogether. Making Bitcoin illegal would likely make the whole
When the first through fourth versions of this essay were written, Bitcoin was the most expensive cryptocurrency in circulation. These days, the three most popular cryptocurrencies are all cheaper. (You can see all of them and learn how to buy some here: https://www.cryptocurrency101.com/cryptocurrencies/ ) Cryptocurrency is a kind of money that’s online only; it exists only in cyberspace. You can’t hold it in your hand or keep it under your mattress like cash, but you can spend it online.
Bitcoins are one form of cryptocurrency; there are others, including Ethereum and the Litecoin network. But Bitcoin is still the most famous and most useful—the one you hear about first, the one everyone else learns about after you do.
There are two main things you need to know about Bitcoin: what it is, and what you should do if you’re thinking about buying some.
First of all, forget about Bitcoin for now. It’s too complicated for most people to understand, and it’s not something you need to know anytime soon—it took several years just to get where we are now with Bitcoin! I think we’re only at around 40% of the whole story—we haven’t even gotten to the
Cryptocurrency, also known as crypto, is a form of digital currency that uses encryption to secure transactions and control the creation of new units. It uses decentralized control in a manner similar to Bitcoin, but with a number of differences. (See our glossary for more definitions.)
The most important distinction is that cryptocurrencies do not rely on a centralized authority to ensure the integrity of transactions. Instead, all transactions are verified by network nodes and recorded in a public distributed ledger called a blockchain.
A second important distinction between cryptocurrencies and other forms of digital currency is that cryptocurrencies are designed to have a fixed supply. The total quantity of currency in circulation can be changed by modifying the code that creates new units or by burning currency through “mining.” Burning the currency through mining serves two purposes: it eliminates the supply of existing units, and it makes further mining essentially impossible. As such, if people stop mining, there will eventually be no more units of the currency in circulation.
One of the things that make cryptocurrency so interesting is the feeling of being left out. The most widely-used coins, Bitcoin and Ethereum, were not designed with the general public in mind. And while they are not intended to be standalone currencies, they are not good for much else. They are like a high-end Swiss Army knife: a lot of uses, but with little to do on its own.
That is why other cryptocurrencies have cropped up, offering more flexibility than Bitcoin and Ethereum. Litecoin, for example, was designed with fewer concerns about security and transaction speed. Monero has been called “the purest form of digital money possible,” because it is based on mathematics rather than cryptography. Even new coins have been made in the name of privacy—Zcash and DASH both emphasize anonymity.
There are different ways to buy these cryptocurrencies. If you want to invest in an ICO (Initial Coin Offering), you can find them on sites like coinmarketcap.com or tokenmarket.net .

Cryptocurrency is a digital currency that uses cryptography for security. It’s used by websites and companies to buy and sell things online. The most popular cryptocurrency is Bitcoin, which has become a kind of digital gold. It’s also used to buy real estate and private jets; the price of a single Bitcoin started at $1,000 in 2013 and reached $19,000 in December 2017.
Cryptocurrency is the technology of the future. It’s a lot like the internet in the early 90s: it’s new, exciting, and full of promise.
Some people think it will change everything – but only if they are dead wrong. A cryptocurrency is a virtual currency that uses cryptography to create a secure and decentralised payment system. Cryptography is used to keep people honest – it keeps banks honest, and prevents cheats from stealing money through fraud or hacking. It is also used to ensure that every single transaction can be verified by everyone else using the same system.”
Cryptocurrency has two main features:
It’s decentralized – no one has complete control over it. Imagine you were at home one day and you decided you wanted to buy a pizza for $20. You’d need to go to your bank account and get the money, then go out and buy the pizza with cash (or credit card). If there was no central authority, no trusted person who could make all this happen for you, who would be able to deliver $20 worth of pizza?
It’s secure – every transaction can be verified by everyone else using the same system. Imagine you were at home one day, and you wanted to send $20 worth of pizza to your
Bitcoin is a digital currency that can be sent from one person to another without the use of any middlemen, such as banks or governments. When you want to spend your bitcoins, the user creates a unique key that is an address. That unique key is then used by the computer to make a transfer of funds from their own account to the receiver’s account, ensuring no fraud and keeping users’ accounts secure.
Bitcoin was created in 2009 by an anonymous developer going by the name Satoshi Nakamoto. It uses peer-to-peer technology to operate with no central authority or banks; managing transactions and issuing money are carried out collectively by the network.
