What I have seen from my experience is trading bots will always eventually run you into losses, especially the ones which are readymade available in the market, you will see them going well for a long time, and then suddenly you will see all your earnings getting wiped out in just one or two trades, this could be due to some bug in the code because these trading companies don't really put so much effort in getting the code audited from end to end. I have seen big companies making tons of money from cryptobots but they make money because they generally have their own trading bots which they get tailor-made from in-house coders only.
