A couple of hundred or so. When I deposit it's always under $100. Let's say I deposit $50, if I get to $100 I don't think it's enough to withdraw but if I've been playing for a few days and I get to $200 I'll withdraw it. Another case would be if I deposit just like $10 to test a site, even if I reach $100 I will withdraw it. It depends a little bit on how it works for me. None of those amounts make the difference for me but I know that in gambling the odds go against us and since most of the times I deposit I lose it, if I win something relatively significant in relation to what I deposited I prefer to withdraw it rather than lose it. I know for a fact that if you have a stroke of luck and keep playing it is normal to lose everything, and in some cases even more. It is better to know how to withdraw in time.
