Many gambling sites have deposit bonuses.
However, if you receive the deposit bonus, there is a condition for withdrawal.
For example, 10 times the deposit amount, etc.
What is the reasonable condition you think?
I think it is fine whatever their term is as long as they wouldn't put up a time limit to play with their deposit bonus,
Because not everyone could play continuously and achieve their desired condition in order to withdraw the bonus.
I think it is great that some of them would give out a deposit bonus so that other player could enjoy more in their gambling site.
