What is a cryptocurrency?
**Needs to be completely changed**
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.
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.
Why would you use a cryptocurrency?
Cryptocurrencies are known for being secure and providing a level of anonymity. Transactions in them cannot be faked or reversed and there tend to be low fees, making it more reliable than conventional currency. Their decentralised nature means they are available to everyone, where banks can be exclusive in who they will let open accounts.
But the same works the other way. People look to invest in cryptocurrencies should be aware of the volatility of the market and the risks they take when buying.
Because of the level of anonymity they offer, cryptocurrencies are often associated with illegal actvity, particularly on the dark web. Users should be careful about the connotations when choosing to buy the currencies.
