Background
You have heard about it on the news or from a friend, but what exactly is cryptocurrency? Don’t feel down if you don’t yet have a firm grasp on this new asset class. Cryptocurrencies can be difficult to understand if you don’t know the basics.
To give you a better understanding of what cryptocurrency is and how it works, let’s go through the history of this relatively new technology, an overview of its inner workings, different types of cryptocurrency, and where this industry could go in the future. Once you get some background information on these subjects, you will gain a much more solid understanding.
History
Cryptocurrencies have gone down a long, winding road in the past decade. Even though the general public has only stumbled upon cryptocurrencies over the past several years, there has been significant work that has led to this point. In fact, cryptocurrencies have a history that dates back more than a decade, to a time when Bitcoin didn’t even exist.
Was Bitcoin the first cryptocurrency?
Cryptographers had been playing around with the idea of cryptocurrencies decades before Bitcoin came into existence. At the time, the question of ‘what is cryptocurrency?’ wasn’t yet fully answered, but that didn’t stop people from attempting to create their own. The most well known of these attempts came from Nick Szabo, a computer scientist who developed a cryptocurrency called Bit Gold in 1998. While Bit Gold was never fully launched, it is credited as paving the way for Bitcoin.
When was Bitcoin created?
In October of 2008, a white paper by the mysterious Satoshi Nakamoto was released. This paper described a decentralised network used to fuel a new cryptocurrency called Bitcoin. It would take years before merchants would begin to accept the new form of money as payment, but slowly Bitcoin began to catch on. Over the next several years, more cryptocurrencies would be launched on the back of Bitcoin and ride the emerging cryptocurrency wave.
Cryptocurrencies go global
By 2014, there were already dozens of cryptocurrencies popping up. Some of these, like Ethereum, would continue to grow and thrive over time, yet others would go bust as quickly as they came into existence. When 2017 rolled around, cryptocurrencies were becoming the darling new niche of the financial world, hailed as a saviour from the “corrupt” financial system. They were bought and sold on new trading platforms. Hundreds of tokens, another name for cryptocurrencies, had been created and their values were quickly rising. By the end of 2017, Bitcoin had skyrocketed in price from $900 to $20,000, and the entire industry hit a valuation of $600 billion. By 2018, it was clear: Cryptocurrencies were here to stay.
What is cryptocurrency?
A cryptocurrency is a digital currency that uses cryptography as a means of security. Most cryptocurrencies operate without the need for a central authority like a bank or government, and operate instead through a distributed ledger to spread power among its community. A cryptocurrency has a set, defined monetary policy, whether it be a fixed limit of tokens or allowing the creation of new tokens based on predetermined rules.
How does it work?
The distributed ledger that holds cryptocurrency transactions is known as a blockchain. A blockchain consists of blocks, which hold individual transaction information. This information is timestamped and posted to the ledger so that each transaction can be verified by other blockchain stakeholders and never be altered. In order to conduct a transaction on the blockchain, users agree to pay a small fee, which helps maintain the security of the blockchain itself.
Let’s say you want to send your friend a small amount of Bitcoin. You create a transaction using your Bitcoin wallet and request to send Bitcoin to your friend’s wallet, agreeing to pay a nominal transaction fee along the way. After you make the transaction request, your transaction gets grouped with other transactions into a block on the Bitcoin blockchain. This block is verified by miners and posted to the blockchain, making the transaction complete.
Through this process, you can send cryptocurrency to anyone, anywhere around the world, with low transaction fees. Want to send $1 million Ethereum to your family in Brazil? Go right ahead! Not only will the transaction usually be completed in a matter of seconds or minutes, it will only cost you a fraction of the fee you would have paid using a traditional money transfer service.
What is cryptocurrency used for?
One of the early appeals of cryptocurrency was that it offers you the opportunity to transfer large amounts of your wealth anonymously without any government or institutional interference. These days, cryptocurrency is used by some owners to take care of routine matters such as paying bills. Others use it as collateral to obtain online loans.
Still others put their digital currency to use by investing in business start-ups. The combination of innovative tech ventures and cryptocurrency seems like a natural fit. You can also use your digital currency to travel the world. Arrive at your destination in the luxury vehicle you purchased with your cryptocurrency or on the airline that readily accepted your Bitcoin.
How to spend cryptocurrency
In addition to transferring money, you can also use cryptocurrency to make purchases. The list of items that you can buy with digital currency increases as more merchants see the advantage of offering a wider variety of payment options.
People have used cryptocurrency to purchase everything from high-end real estate (with Bitcoin payment service providers like BitPay) to pizza (services like Pizzaforcoins allow you to order from chains like Domino’s, Pizza Hut, and Papa John’s). In fact, the first purchase ever made with Bitcoin was two pizzas for 10,000 Bitcoin.
You can even use your Bitcoin to hitch a ride into space aboard Virgin Galactic. If your lifestyle is a bit more down to earth, you can now spend cryptocurrency at online retailers like Overstock.com (Overstock has partnered with Coinbase for Bitcoin payments.)
How to buy and sell cryptocurrency
Now that you know what cryptocurrency is, it is time to buy some for yourself. Unfortunately, cryptocurrency can’t just be bought on any exchange; it requires the use of a cryptocurrency exchange or online trading platform to make a purchase.
There are many cryptocurrency exchanges available for you, but few are as easy and secure to use as Coinbase. With Coinbase you can buy and sell the most popular cryptocurrencies — such as Bitcoin, Ethereum, Litecoin and more — in an instant and with low fees.
Once you have purchased cryptocurrency, you can then use the Coinbase Vault to securely store your cryptocurrency until you are ready to sell it, spend it, or send it to a friend.
