This sites domain has been registered since 2014 but I have never heard of the gambling site before. Why not use one of the trustworthy casinos on this forum? We have many of them. You can go to gambling board to see some for yourself. Check their reputations.
I check the review of this site on Trustpilot and it is poor

I do not believe in Trustpilot fully but in case like this, I believe and will not use that site.
You're right 22bet has been registered since 2014 but I have not been gambling using 22bet they keep sending me message asking me to join 22bet but i keep ignoring there messages,I think they are looking for customer's,I don't consider this site trusted at all.
