Sorry this happenned and to be honest I kind of perused the post didn't really wrap my head around the whole story but here's the thing. There's no free lunch, nobody does anything out of the goodness of their own heart.

I guess you have to ask yourself why is this guy going to cut me in on the gains, but not make me accept the risk. You mentioned in the post how in the case of any losses your money was backed by his.

Also if someone is a good trader they should be able to run up their own bankroll and play with that. This sounds like Bitconnect. My response to Bitconnnect throughout the whole saga was hey if you have this trading bot that's so great, use it, make money and roll that into scaling the operation, you really don't need other peoples money.
