The bankroll was around 3000 bits, I've lost most of it

, there is a vulnerability, the max bet is just 100 bits, but the people hacked it to bet more.
Based on the bet history, most bets that are higher than 100 bits were lost bets. I did not check all pages of the bets history but I can see some 10,000 bits losing bets. Shouldn't you make some profit from those 10,000 bits losing bets? That's even 3x bigger than your bankroll. Coming up to the word "hacked", is it appropriate to accuse player hack your site while there is no rules on your site about the max bet? You allow the bets and there are losing bets too, how can it be called by hacked?
but it seems that someone modified the request to make it bigger, and our backend code had some error to validate it.
