I believe Sportsbet.io always did Black Friday Bitcoin drops (free BTC not even with wagering requirements) and a couple of years ago the big one was 1 whole BTC!
They always do and I think they are one of the few who have promo all the years around. Stake does the same. Thing is these promos are a very good way to stay connected with the community and successful projects do it all the time.
Thank you very much for that information, Sportsbet.io and stake.com are casinos that really have the highest reputation here in the forum, they are the casinos that I like to make accounts and I think I am able to put my KYC if necessary because this type of casinos make everyone trust them, I think that Duelbtis can also be included there, it is a casino that is not as old as these big ones, but it is in a very good position, I have seen how many people They have good references about that casino, the casinos that have more time are the ones that many players look for, and it is curious that they do not have bonus promotions with wager, I like that.
