Bwin appeared in Portugal last season and they have since then sponsored the Portuguese Super League. Suddenly everyone was opening up accounts and betting with them. I first got interested about betting because of a friend of mine who had an account there. After reading some reviews of websites I decided not to join with them because they are simply not reliable. I have had accounts with
Ladbrokes, Betcris and
Betfair and never had problems with payouts.
All my friends have accounts at bwin but the truth is none of them wins money betting, so no complaints... I think some of their managers were involved in racing fixing scandals, although I can't say where, just remember seeing it on the national newspapers.
My advice from what I've read here and at other forums is STAY AWAY FROM BWIN.
