A large number of low spread forex & CFD brokers have in recent years started offering cryptocurrency CFDs to their clients. This became particularly popular during the huge crypto bull market of 2017, but the trend has continued in the years after.
A unique thing that separates cryptocurrency trading from regular forex trading is that the crypto markets are open 24 hours a day, 7 days a week, while the forex market is completely closed for trading during the weekends. However, many low spread brokers that offers CFDs on cryptocurrencies have for practical reasons chosen to follow roughly the same trading hours as the forex market. For this reason, trading in crypto CFDs rarely occur during the weekends.
