To learn how to trade well, I recommend that you pay a teacher who has a lot of experience. On YouTube you can find the person that you think is a professional and you want to learn from him. If you try trading by yourself you will lose more money than if you would learn from a professional
You should indeed learn from people who are already professional in trading, so you can immediately master the crypto trading techniques and the risk of loss is also small.
if only learning from youtube or other online media in my opinion it will not be maximal and will only confuse it.
I think learning from social media may not all the time confuses beginners who want to trade.As long as you will understand its deepest meaning,then even without a teacher it will still work.But if you have some friends who are already traders,then you can also seek suggestions from them.In the end,your own experience will still be your best teacher.
