This is the second year in a row that I'm receiving money in my 1xBet balance as a birthday present. Last year it was around 10$, I managed to turn it to 60$ and lost it all at once. This year I got around 20$, tripled it, and withdrew lol. The funny part is I did not make any deposit since November last year. Kinda nice of them, don't you think? Does a bookmaker you play on do something sort of this apart from free slot spins that you can redeem your winnings (play x game and double your winning in case you win or play z game and get back 50% of your bet in case you lose) only by playing your own money later?
I had not received any that kind of surprises so far from any of crypto gambling houses but I remember that I have got birthday wishes from one of the reputed house. Moreover, I am not using my regular email id for gambling registrations. For security purposes, I do use my secondary email while registering with gambling houses and I do rarely check that email for any update which might be a reason that I have not got any surprise gifts from gambling houses on my birthday.
