It is now 100% sure, 1xbit is owned by 1xbet (even though they say they aren't) look, I created an account using Korean VPN:
Does this matter at all? We all know that both are the worst gambling sites that have ever existed. They mention useless rules all the time and block the user's account unnecessarily. Forget about the winnings; they don’t even give back a user’s deposit. Hence, I advise all the newbies to avoid sites that have “1x” in their name. These sites just do large-scale promotions, and innocent newbies fall for their traps. It’s best to avoid these sites at any cost..
From the start I was suspicious of the names 1xbit and 1xbet, these two really always indicate something that makes many people think the same thing. But because I'm not really interested in this casino which has a clear bad reputation on the forums. Moreover I think this thread is no longer active. Their representative has also disappeared, it seems they will not be coming back to resolve this problem. So regardless of whether 1xbit and 1xbet are the same, it is better to avoid them. There are many trusted casinos on this forum with unquestionable reputations.
