Isn't this part of the same ring of casinos under the same domain as vegascasino, sportsbet etc?
If it is then that is just sad and anything to do with bitcoin casinos and .io domain should be instantly revolted against and seen as a possible scam being run. You should be aware and not give even an ounce of you bitcoin to them.
Bitcasino.io is super legit and have been for years.
Vegascasino.io is legit as well but I stopped using them because of some minor but annoying BS they pulled.
Seriously though, bitcasino.io is my casino of choice. I've received free promotional items in the mail, received an Xbox one (plus 2nd controller and battlefield) for my vip gift and I've received all sorts of great promotions and bonuses.
In the starting days this might have served all the users in a better way with much legitimacy. Now due to lack of development the site might have experienced a bankruptcy. This might be the reason that our Op haven't got the withdrawal even after waiting longer.
