Welcome bonuses are promotional offers that crypto casino sites provide to attract new customers. These bonuses typically come in the form of first deposit matches and free spins on selected slot games. Deposit bonuses are additional rewards given to players when they add funds to their account, while reload bonuses are incentives for existing players to continue depositing and playing. To claim these offers, players usually need to meet specific requirements such as minimum deposit amounts or wagering requirements before they can withdraw any winnings.
