On your message I want to answer the folk wisdom " live forever, learn forever." But here I can not agree with you that no matter how much you do not draw knowledge about trading all you need to try in practice. And to get a positive experience, you need to follow the main rule of trade to buy coins when the price is reduced, and to sell when the price is at its peak. That's the whole secret, so good luck to you in this very difficult matter!!!
I don't think this is a secret, but it's a truth that everyone knows about, although very difficult to do if you are human and not a robot. Humans have emotions, and these emotions can kill your profits if you are driven to much by fear or greed.
