I disagree. The casino may choose to block any account for any reason. There is no evidence they operate legally as they do not hold any gambling licenses, and therefore are not subject to any legal regulations.
This is unfortunately the situation that has been discussed in this thread from the beginning. Just as it is impossible to prove that 1xbit blocks accounts without reason, it is also impossible to prove that the complaints are justified. Just word against word. It is your choice who you want to believe. I believe 1xbit, because they are honest with me for few months already. It seems completely natural to me that I have good opinion about 1xbit.
It is not unfortunate if they decide to hide company information so damaged clients have no legal protection. What is so difficult to understand about that? Show me one legit casino that does that. Clearly, these people are operating an illegal casino, and these are verifiable facts, not just my opinion. How can you possibly believe such a casino when so many customers complain about them?
