Probably not. Generally most sites require that you make a deposit (I use Neteller for speed and security) and they will cash you out using the same route (makes sense for security).
My first deposit with
Titan was late last year for $50. I've withdrawn at least double that amount (my smallest w/d was $8). Withdrawals take about two days max. Not too bad. Neteller provides a place for me to sock away money so that I don't TILT-it away.
Bottom line is go ahead and make a deposit at
Titan and you can start withdrawing your winnings. You should always make an attempt to review their w/d restrictions (time, amount, No. of times to bet a bonus, etc.).
Iceberg.
