I agree with you that I recalled that I don't know casinos that require x times of wagerring from (deposit + deposit bonus) value but I am a human and can make mistake or I simply missed such casinos. If Bitinity knew such platforms, he can share with us so we can explore something new or at least not know but missed by us.
I think we found one already. Spinly.io is one of them. According to the screenshot iv4n shared, his deposit and bonus were 0.6 SOL, and he had to wager 54.77 SOL, which is 90x of that amount. This is insane, to be honest. Probably Bitinity saw the same rules in other casinos as well, as he is more active in gambling than some of us. I am not regular, though.
In this case, I would ask Spinly.io to lower the wagering requirement for the deposit and the deposit bonus as well. The 45x wagering requirement on the bonus is enough already. You don't have to impose a 45x massive wagering requirement on the deposit just because someone took the deposit bonus. You have to be competitive to grow in the market.
