1xbet or 1xbit? both side seems similar but did you watch Seri A football and there are have an official partner from 1xbet, actually 1xbit have confirmed as scam gambling site with many user blocked their account when try withdrawing but confused with the similar name 1xbet keep exist as partner of Serie A almost two years. I don't think 1xbet and Serie A will be partner is site connected with 1xbit as scam gambling site because Serie A want keep their reputation.
Both sites are 100% connected and there is a lot of proof suggesting the same. There are other sites like Melbet etc which are connected to these sites too. It's a huge scam organization operating in broad daylight.
1xbet also has a ton of scam accusations against them, but they aren't talked about a lot in this forum since it's a FIAT casino primarily.
