Bottom line, when you use 1xbit, You have way too many odds against you winning a bet and withdrawing your winnings
It's true for many casino and sportbooks. When you will win big they will start looking for ways not to pay you but keep losing, they are fine. They will not ask for KYC, video verification, IP check and all sorts of high tech things.
I do not think 1xBit will be able to solve any of the cases even if they want. It's all messed up, the old ones but for the new ones they can move forward with case by case basis.
