My guy lost huge some amount of money in the name of using trading bots, Some bot used to work at the beginning but when it gets at some point things begins to fall apart.

I highly discourage the idea of people borrowing funds to trade or investing a borrowed fund, let alone trading without their own money. Trading involves risk and that risk should be taken just with your own money and not any money but basically the amount of money that is losable to you, in order to be able to bear the loses you may incur. In case where you want to manage other people's account you have become a professional trader to do that.
