payment method bonus is a special promotion that some online casinos offer to encourage players to use specific payment methods. These bonuses can vary greatly in terms of their size and type, from deposit match bonuses to free spins or even cashback offers. The specific payment method bonus will depend on the casino's ongoing promotions and may only apply to certain payment methods, such as a specific e-wallet or cryptocurrency. However, not all casinos offer these bonuses, so it's best to check the promotions page or contact customer service for the most accurate information.
