What is cryptocurrency? Full explaination

Cryptocurrencies such as Bitcoin and Ethereum are decentralised digital currencies on the blockchain.

Some of the things that cryptocurrencies have in common include:

Decentralisation – The decentralised nature of cryptocurrencies means that no single government body or financial authority has control over them
Blockchain technology – All cryptocurrencies use a variation of blockchain technology (a kind of public ledger) to score records of each transaction.
High level of security – Each cryptocurrency transaction is secured through advanced cryptographic techniques that make it almost impossible to counterfeit
Trading cryptocurrencies on our MetaTrader 5 platform means taking a position on a cryptocurrency pair when you expect it to rise or fall in value so you can make a profit when your prediction is correct.

Trade Bitcoin, Ethereum, and Litecoin pairs without owning them. Our cryptocurrency pairs quote a cryptocurrency such as Bitcoin against a fiat currency, such as the US dollar.

Similar to Forex trading, you must understand when to buy (or "go long") and when to sell (or "go short"). In Forex trading, you'll buy a certain currency pair if you think the value of the base currency will rise. The opposite is also true: you will sell a certain currency pair if you think the value of the base currency will fall.
