1xbet have physical casinos and betting outlets in different country all over the world, they are not 1xbit as Haunebu assumed, 1xbet is 1xbet and 1xbit is 1xbit, based on what I know.
I think that bet-b2b uses own CMS to create many other casinos - 1xBet, 1xBit, Casino Z, JVSpin Casino, Melbet Casino, Betandyou Casino... There are many more and they all use bet-b2b. It's also curious that bet-b2b and 1xbet.com had exactly the same logo colors years ago. I believe, bet-b2b creates many casinos, scam with them and make money. They try to invest more in 1xbet fiat casino and make it popular instead of running a traditional scam scheme, 1xbet is their brand casino, main face.
Good observation that's why we should avoid any of those casino which have are related to bet-b2b since maybe they are do scamming for long time so for the information we gather in this thread hopefully it will spread so that people would be aware about what's happening to them. For now 1xbet is famous on fiat casino since this is well promoted by known influencers and other big entities so provably their focus is with this site since they can still gather a lot of money compare on 1xbit where everything is totally gone since there reputation on crypto space is really so bad.
We should not wait for the worse to come if we doubt to quit and its smart decision to anyone to avoid then find another reputable alternavive for their own safety.
