What's the essence of the promotions without a good RTP. Will the promotion cause traffic? Yes, but not for long. So what's the essence !
True, but in this case, when the gambling site is properly registered, I don't think we need to discuss the RTP again for that matter because they already have their own audit and regardless of the logic, when the gambling site is seen well, it is certain that the RTP there is already tested.
I personally prefer promotions in this case but only for a few sites and some trusted casinos
