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..
1xbit or 1xbet, they play very sensibly as they will not scam you in the start if you are a low wagering gambling. They will also let you withdraw small amounts but as soon as you deposit big amount or try to make a high withdrawal, they will scam you and never let you withdraw the money.
Its strange that even after too much awareness provided on bitcointalk forum, people still fall for their scam. The reason could be that they also advertise on social media and for a an average gambler, they don't care to investigate and get feedback of the platform before depositing there.
It's really unfortunate that platforms like 1xBit and 1xBet have been engaged in such deceptive practices and still they are running their business. They are operating in such a anonymous way that it is impossible to track and stop them.
