Do signup bonuses hurt or help you guys? It has always hurt me.

Two or three different times at different casinos I won a fair amount of money and wanted to cash out but most do not allow you to cash out minus the bonus. So basically they have always only hurt me rather than me benefit from them.
What are some of your experiences?
Yeah, I've never had very good experiences with sign up bonuses. It's mostly like it's just a big tease and then I never end up really seeing the bonus. You have to wager way more than what should be reasonable before you even see your bonus. I remember playing fiat sites and they just give you the sign up bonus right away after your deposit with no limits or wager stipulations.
Fiat sites match up your first bet with cash up to a fixed amount and this usually doesn't require any rollover. In reality fiat sites are way ahead of bitcoin ones. I love Betfair
