Cryptocurrency is a form of digital money that is designed to be secure and, in many cases, anonymous.

It is a currency associated with the internet that uses cryptography, the process of converting legible information into an almost uncrackable code, to track purchases and transfers.

Cryptography was born out of the need for secure communication in the Second World War. It has evolved in the digital era with elements of mathematical theory and computer science to become a way to secure communications, information and money online.

The first cryptocurrency was bitcoin, which was created in 2009 and is still the best known. There has been a proliferation of cryptocurrencies in the past decade and there are now more than 1,000 available on the internet. Bitcoin soared as high as $20,000 at the end of last year before crashing back to around $6,000 now.

Here's everything you need to know about cryptocurrencies.

How do cryptocurrencies work?

Cryptocurrencies use decentralised technology to let users make secure payments and store money without the need to use their name or go through a bank. They run on a distributed public ledger called blockchain, which is a record of all transactions updated and held by currency holders.

FAQ | Bitcoin

What is it?

A digital currency, used to make payments of any value without fees. It runs on the blockchain, a decentralised ledger kept running by “miners” whose powerful computers crunch transactions and are rewarded in bitcoins

Who invented it?

Satoshi Nakamoto, a secretive internet user, invented bitcoin in 2008 before it went online in 2009. Many attempts to identify Satoshi have been made without conclusive proof

What’s it for?

People see value in money free from government control and the fees banks charge; as well as the blockchain, to verify transactions. Bitcoin has been seen as a tool for private, anonymous transactions, and it’s the payment of choice for drug deals and other illegal purchases

Is it worth anything?

Yes. As of December 2017, there were around 16.7m bitcoins in circulation. Each was worth around $14,000 after a recent high of close to $20,000 for a market value of $230 billion.

Units of cryptocurrency are created through a process called mining, which involves using computer power to solve complicated maths problems that generate coins. Users can also buy the currencies from brokers, then store and spend them using cryptographic wallets.

Cryptocurrencies and applications of blockchain technology are still nascent in financial terms and more uses should be expected. Transactions including bonds, stocks and other financial assets could eventually be traded using the technology.
