A blockchain is a shared digital register of recorded data. For cryptocurrencies, this is the transaction history for every unit of the cryptocurrency, which shows how ownership has changed over time. Blockchain works by recording transactions in ‘blocks’, with new blocks added at the front of the chain.

Blockchain technology has unique security features that normal computer files do not have.

When you buy cryptocurrencies via an exchange, you purchase the coins themselves. You’ll need to create an exchange account, put up the full value of the asset to open a position, and store the cryptocurrency tokens in your own wallet until you’re ready to sell.

Exchanges bring their own steep learning curve as you’ll need to get to grips with the technology involved and learn how to make sense of the data. Many exchanges also have limits on how much you can deposit, while accounts can be very expensive to maintain.

Cryptocurrency markets are decentralised, which means they are not issued or backed by a central authority such as a government. Instead, they run across a network of computers. However, cryptocurrencies can be bought and sold via exchanges and stored in ‘wallets’ .

Unlike traditional currencies, cryptocurrencies exist only as a shared digital record of ownership, stored on a blockchain. When a user wants to send cryptocurrency units to another user, they send it to that user’s digital wallet. The transaction isn’t considered final until it has been verified and added to the blockchain through a process called mining. This is also how new cryptocurrency tokens are usually created.

Bitcoin is the first and most well-known, but there are thousands of types of cryptocurrencies. Many, like Litecoin and Bitcoin Cash, share Bitcoin’s core characteristics but explore new ways to process transactions. Others offer a wider range of features. Ethereum, for example, can be used to run applications and create contracts. All four, however, are based on an idea called the blockchain, which is key to understanding how cryptocurrency works.

Cryptocurrencies are the first alternative to the traditional banking system and have powerful advantages over previous payment methods and traditional classes of assets. Think of them as Money 2.0. — a new kind of cash that is native to the internet, which gives it the potential to be the fastest, easiest, cheapest, safest, and most universal way to exchange values that the world has ever seen.

Storing crypto is similar to storing cash, which means you need to protect it from theft and loss. There are many ways to store crypto both online and off, but the simplest solution is via a trusted, secure exchange or cold wallet
