Please give me an insight about this, Is 1xbet and 1xbit still running by the same company? I've seen some threads here about 1xbet and 1xbit having the same UI on their casino which makes them suspiciously ran by same company. 1xbet is currently aggressive on their advertisement and partnership especially on e-sports scene. Which make them trustable because of money they spent heavily on their marketing.
Some of the posters above already provided a ton of proof specifying how both of these shady sites are linked. I would just like to add by saying that you shouldn't trust a company blindly just because of their advertising deals.
That's just naive thinking if you ask me. You should focus more on their reviews in various credible sites in order to trust them to some extent.
