Starting trading is not a big deal, A person can just decides to start forex or crypto trading without knowing the ups and downs of this business, the real challange comes when your in the process facing the losses, emotional stress, fomo etc. and that will then determine if you have started trading or not, you can not say you have gotten a job inside a big company when you just went in to write the test and you where not qualified enough for the job,
So is it in trading also until you start to learn without giving up, then have you started trading because that point where you face its challenges and that is its own type of test. The big question is if your qualified for the job.
And being profitable in trading is quit not really easy, but me personally back-testing is the best tool as long as you want to be profitable all tough there are still other ways but me I do think that back testing is the best.
