If you understand and have an idea of forex trading, I think you should also look into cryptocurrency trading ,even if you're not trading at least you really need to have an idea of how it work, you find out that cryptocurrency might even be easier.I dont know much about crypto trading. But in forex trading, there is something we do which is called compound planning. We trade certain amount per day based on the amount we have in our account. This is to prevent greed in taking too much trades, and to be able to control how much percentage we put in.
