It is best to learn the basics first about trading well and correctly and try to learn to read charts from experienced traders, and practicing on a demo account is also important because there you can do and learn with non-real coins.
and whatever you learn doesn't mean you will become a great trader, it all requires a process and experience that will help you become a very careful trader because you learn from mistakes and losses that will not repeat the same mistakes.
I don't know Buh I think there is no demo trading for crypto, we only got that in the forest space. Sadly most newbies don't go deep into trading learning much about it, they learn the basics which could be just executing trade but there is more to crypto than just placing trades, that's what most of them don't know and they get rekt within a short period of time, I did advice strive for mastery, not only learning the basics or knowing the theory part, they should try to put their knowledge in practice by starting with a smaller capital and try growing it.
