Cryptocurrency trading is the buying and selling of digital currencies such as Bitcoin, Ethereum, Litecoin, Ripple and others. There are applications and trading platforms that allow you to trade cryptocurrencies through contracts for difference (CFDs), which allow you to profit from changes in the price of cryptocurrencies without actually owning them.
Before you start trading cryptocurrency, you need to do enough market analysis and understand that it is a high-risk and volatile market where prices can fluctuate rapidly.
