Been here for almost 2 years and counting but still me myself don't consider a pro in terms of analyzing what's the crypto to invest and gain profit after like a couple of months or for long term hodl.
A real professional will never call himself a pro. he knows that he needs to learn about crypto more and more. The longer he trades, the better he understands that he does not know a lot of things about this business.
I think that if someone can make a regular profit from trading and investing than he is good enough to be considered a pro. It may take a few years of detailed learning and practice to become a good trader.
