Or maybe you should all do a thorough research of who makes complaints, why they do it and whether they are dealt with and how? Also check on what basis you issue your opinions - on the basis of facts or the opinions of others.
Because maybe it is that 1xbit and 1xbet are fair casinos and organizations such as Barcelona, Confederation of African Football and others have good research and have better checked who they work with?

FC Barcelona - https://www.fcbarcelona.com/en/news/1263451/fc-barcelona-adds-1xbet-as-a-new-global-partner
CAF (Confederation of African Football) - https://www.cafonline.com/competitions/sponsors/

Maybe you should check if the owner of 1xbit and 1xbet is one company, or you don't know it and you are still speculating?
Maybe the time has finally come to check if all these negative opinions about 1xbit come from facts or are they simply duplicated unverified opinions?
