Who would even use a birthday in a casino? I would never bother to join a site which requires a lot of personal information other than an email address. Why would a casino ask for a birthday? I can't remember if I was required any such information while joining any casino. Even if I was required, I would never bother to give my original birthday to a casino.
This is the second year in a row that I'm receiving money in my 1xBet balance as a birthday present.
That's a nice gesture to surprise and satisfy the client on an extreme level. I'm not sure if you are really appreciating 1xbet or promoting this site. Afaik, 1xbet is a scam casino and has a lot of scam accusations in the forum.
