A warning, do not bet with Betser. I had an account there, got some free bets and thus some bonus money. If you make bets with bonus money as well as real money all money will be turned into bonus money with high rollovers.
After I won a reasonable amount with the bonus they added the term to their T&Cs that you were not allowed to bet more than 50$ with a bonus active. So now they have confiscated 2000 Euro of my balance on this term they have retroactively smeared into their terms (it looks ridiculous). Out of this money roughly 600 Euro would have been a real money balance if not for their absurd terms.
Their regulator, the MGA, seems to back this behaviour.
