I think the problem here is that you do not really understand "why" we do not trust this. You think its working or you even maybe "know" its working so you have no idea "why" we are not trusting it. And I can totally understand that. However the reality is that if you do not accept openly that "because of house edge there is no way of winning in gambling long term" then nobody will trust you, that is plain and simple.

If you went out and said "this system allows you to gamble longer without losing but eventually it loses too because of house edge" then people would believe in you, hell there are gambling bots everywhere and they all accept that simple fact.

However, you keep saying "you enjoy losing, otherwise you would have used our system" sounds like using your system would make us win all the time and we all know its impossible as long as there is a house edge. So come out and say that your system would be better than manual and would have higher chance at winning but eventually even your system will lose because of house edge and people may start looking at you differently.
