Pretty sure it can take ages because trading is too complex. You need to learn different things for you to master it.
It's possible, but I don't think it will be long even if it takes time. I think 3 months is enough to understand even if it is limited to trading basics. Learning to trade will never run out, but if you continue to do with hands-on practice it will be better, theory alone is not enough for trading. The change of the trading market is also very fast, traders must always follow it to continue to survive and make profits.
However, the best tip in this case is to always pay attention to the development of each asset you have, from how it is used, the development of the project, and how it is needed. continuing to do research all the time and moving based on the considerations of the results of the research you do can make you a good trader. some people out there just move on by the hype, and follow in the footsteps of others.
