Cryptocurrency trading involves speculation regarding the price movements of cryptocurrencies. Cryptocurrency is digital money secured by blockchain technology. Cryptocurrencies can be traded in two ways. One method is to use a CFD trading account, and the other is to use an exchange to buy and sell the underlying coins. CFDs are derivatives that allow you to buy and sell coins directly on an exchange, while allowing you to bet on price movements without owning the coins. You can also invest in cryptocurrencies by purchasing them through certain broker-dealers and crypto funds.
