@Omar, hey, you might want to give the official website another look. It's pretty clear in there – after you create a demo account, the next step is setting up a live account, and you gotta go through the KYC process. They lay it out that when you're picking an account, you get to choose the trading platform you fancy. For trading crypto, you'll need to create an FBS Crypto Account, and that means rolling with the FBS Standard Account on Metatrader 5. The minimum deposit that you need only $5.
The crypto action happens in Metatrader 5 and its own trading app, not Metatrader 4. So, if you're rocking a Metatrader 4 account, you won't get in on the crypto action because MT4 is initially set up for Forex and has limited assets . Just a heads-up, into this article.
