The simplest method is obvious, you need to watch youtube videos to become good at trading, but you will not be getting good at it just yet, you will learn how the good ones are doing. If you like to read then read, if you like to watch then watch, if you like to listen then listen because all kinds of studying is available for people who learn anyway they feel comfortable with.
After you "learn" how they do it, then you open a demo account somewhere to test for free, and you start to trade according to what you learned, if there is a big loss somewhere you go back to your learning and see what you did and what you should have done and what's wrong, sometimes nothing is wrong and you were just unlucky but still check it and learn from the mistake. When you do all of these for a while, then you can start with small amounts and depending on your results could grow bigger and bigger. Simple as that.
To this I will add that you need to verify the nature of the information that you are receiving, I say this because nowadays anyone can open a YouTube channel about trading and talk about all kind of strategies that you can implement in the markets and you can easily see they do not know what they are talking about, but this only becomes obvious once you know how to trade, so there are a lot of newbies learning from videos that are given completely mistaken information and they have no way to know this is the case until it is too late.
