Online casino is a high-risk but profitable business built on mathematics and probability theory. To prevent abuse of bonuses, operators set additional conditions that must be met before making payments. The trick with wagering requirements is to make the bonuses profitable for the casino. This is why the wagering requirements usually state how many times the amount of money deposited must be wagered before a withdrawal is possible. Especially when the casino is young and hungry and must call players loudly. At this stage, bonuses can make up a significant share of GGR! In the future, when the casino gets good involvement, bonuses can be 20-30% GGR to support marketing.
