For me it is basic, if they comply with the basic functions such as being very clear about the Deposit processes and especially the Withdrawal of Funds, it is enough to start, when the casinos give the bonuses with their respective wager, it is necessary that they comply with them so that it does not generate any kind of inconvenience for users, I think that when a user tries to withdraw their earnings after having won something due to a bonus and fulfills all the conditions and it is not possible, it is already an indication of a lot of inconvenience, I think that these things are very delicate, the main thing is that a casino when it starts fulfills what it promises.
