Welcome to Bitcointalk forum guys , interesting site and interesting thread because you even reserved the first 3 number post and I don't know what's the use of that a lot.
also the Site name almost similar to the RainBot of bitvest lol but of course that's not connected by all means .
Hey guys, it's come up a few times, even though it's clearly stated in our graphic. We do offer sign-up bonuses, and we encourage you to visit rainbet.com/promotions to check out active promotions.
How much is this Sign Up bonuses ? maybe a clarifications will help lessen the questioning here.
