1xbet in Spain, 1xbet.es only accepts deposits in fiat currency, it doesn't handle cryptocurrencies, so I don't think what FatFork says is proof that they are a scam.
I understand that 1xbet.es is registered as a separate company to meet legal requirements in Spain, but I don't understand how this means that it can't be managed by the same owners as 1xbet.com, and all other brands from the same group. Why would they use the same name, logo and software?
I have provided evidence to prove that 1xBET and 1xBit are connected platforms (despite their claims to the contrary), but it is up to you to decide if they are a scam.
1xbet.es, the sponsor of Barcelona, is not a casino scam.
How exactly does the sponsorship of a big club prove that they are not scamming their players?
