First of all, I apologize for being against paid courses. So, I checked out some courses that my friend shared. Some of them summarize all the knowledge so you can easily understand more than what you would by searching on Google by yourself. They also provide some tricks, some good, and some that really don't show up on the internet. (But they are not a tool for a 100% win in the crypto market. They simply offer a better chance than if you didn't know anything, giving you a small chance to win)
