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?
nah..i have got my signup bonus from all sites that i have visited..
out of all cloudbet was awesome.
Yes, Cloudbet has a better system, since the bonus is released in small pieces as you play.
I managed to break away from all gambling, but Cloudbet was one of the more interesting memories.
