In some online casinos players may find no deposit bonuses with withdrawal restrictions. In these cases, you will need to make a deposit first to withdraw your winnings. This applies even if you’ve completed the wagering requirement. That’s why it’s very important that you take a look at the terms carefully.
The reason for this is the strict state regulations to which online casinos are subject. They must be able to guarantee that deposits and withdrawals are made by the same person who has registered at the casino.
