I passed a 50k account, which i’m still trading happily and collecting profits.
First of all, the trading is hard in general, not only challenges. So, if you have mastered your trading strategy already and if you are consistent with it, then passing the challenge must not be that hard. Many traders lose their funds in accounts because of inconsistency and emotions, which leads them to overleverage and overtrade. It is quite common for newbies..
Secondly, of course it is possible to pass the challenge in under the month. It is possible to pass after a week as well, but there is no need to rush. Take your time, stay consistent and true to yourself and passing the challenges will not be a harsh time for you. Good luck!
