Mentors can promise profits routinely without you seeing, but rest assured they are not able to achieve maximum profits in trading consistently and I never believe that there are mentors who are able to do that. Trading is a difficult activity and even if you are experienced enough, there are times when we will lose because the market is really speculative. Look at mentors who don't promise anything and instead they want to share trading methods in a transparent way without tempting big and consistent profits.

Mentors are also human and they make the same mistakes as we do, only in terms of experience they are much better and are able to minimize the risks resulting from trading by having the knowledge and experience they have.
