if I start a casino with 3000 in the bank, am I a scammer? If I start with 2000 in the bank, am I a scammer? 1000? At what point am I a scammer?
It's a scam bound to happen when the casino doesn't have a safeguard against winning more than the bankroll. If the maximum profit per bet is $30, you can have a casino with $3000 bankroll. By the time users have won $1000 in total, the maximum profit should be reduced to $20. That way, you'll never run out of money and never have to scam. You may run out of users but at least you'll be honest.
