I was given some free credit on a sports betting / casio site the other day.
I was told I had to play the amount 5 times before I could withdraw. So yeah you are right pretty much.
I actually played 5 times the amount and was up a little. maybe 0.09 worth.. then I got risky and lost it all. Damn black jack !
now a days there are many dice sites offering free bonus bitcoins that is the easiest way to get free bitcoins.On this forum you can join any sig campaigns which can also give you some good bitcoins
I think that most "free bonus" sites will usually give away free bets and will force you to bet your "bonus" several times over prior to being able to withdraw. On a expected value basis these bonuses are much smaller then advertised.
