It is not recommended to chase after the top-ranked traders. I often act as a follower myself, especially those traders with fewer than 90 days but have astonishingly fast increasing rewards, most of them are traps. Because I have found that many traders I once thought were amazing often have a degree of randomness, their success may just be a coincidence of being at the right place at the right time.
To avoid such traders, please try to find those with a very high number of days, which indicates that the trader's mindset is more upright. Because traders who often start over definitely do not want others to know about their past. It is very likely that they have often faced liquidation in the past... it is very likely that this trader will disregard the followers.
