Is there a list of casinos out there that don't have any wagering requirements? Off the top of my head, only freebitco.in but I'm sure there are more.
Freebitco is simply not only a casino or in fact, it's not a casino. It was designed with many other features. If I'm correct, they act as bank and offer interest on the savings LOL. Therefore, you must not mess up freebitco with other traditional casino.
I can't remember if there's any single casino which offer no wagering requirements on no bonus deposit.
