This is how most casinos and gamblers refer to a normal deposit without a bonus. This term is clearer than "regular deposit" in my opinion because it is rare to find a casino that doesn’t offer deposit bonuses. And beside that the term I used can be found in the T&C of most casinos while searching about how much wagering you need before requesting a withdrawal.
To update the list I would appreciate it if someone could share the casinos with a wagering requirement of 3x or more, and I will add it to the list. As many users have suggested, it is best to only include casinos that are discussed on Bitcointalk. I couldn’t find more than what’s in the list for now.
Researching casinos without regular incentives is uncommon, and betting on these online casino games without bonuses is an absolute no-no. As consequently, bonuses encouraged players to put in more effort when playing casino games, checking out the odds that makes the double fold of the capital invested. Adding to the list mentioned, if something goes wrong and it is not disclosed in the thread, the OP will hold you liable because you are the one who recommended a gambling site with bonuses.
