Personally, I tryed many times to learn about it but I am still beginner on it and barely I unterstund something.
It can be done through trading but only if you understand the market cycle and market psychology. I am also trading and consider myself as a beginner as well. I know that I am suppose to not trade in hypes but sometimes I can't stop myself from buying the coin because of the possibility that I can profit from it. I am suppose to not join pumps and dumps but there are times when I join because I also profit from it sometimes. I know that I am suppose to plan my trade but sometimes I go all in one coin without thinking of the take profit or stop loss and just keep on holding even though I know that I bought at the top. I know that I am suppose to buy low and sell high but why is the opposite happening? Sometimes I buy high and sell low because I lose hope that the coin will rise but after I sold it, the coin rise up and I am suppose to be in profit but I am at loss. These are my mistakes and I hope you learn from it. These are how not to trade and to make your money half not double it.
