Everything you said is correct, op, but you know that even if traders know a lot about crypto trading theory, when it comes to actual trading, they still haven't been able to properly and correctly apply what they learned in theory about trading.
Because no matter how deep they know about trading theory, if the technical and fundamental analysis is wrong, even if what they studied is correct,
the results will still not be correct.
There is difference between learning and doing the actual trading, it's like learning swimming versus doing swimming in real water. During the learning phase one can use techniques like paper trading and one can infer from these techniques that he is now fit for trading but these techniques won't work much when you start doing real trading with money behind.
The art of trading is learned after you spend time doing actual trading with real money, try different strategies and figure out which one works for you and which is not for you.
