This is the truth and reality that every newbie must hodl on to.
Trading with funds that you can afford to lose gives you peace of mind, and the required calmness to trade efficiently.
That way, you are not under any pressure to perform.
Actually, this is a simple thing. you just don't need to put all your money into trading. however, it has a big risk. if you want to be serious about this, that's very good, but don't ever take a greater risk than what you can bear. my suggestion is to use your assets below 50%.
