Withdrawing from Bodog before clearing 10% bonus

[StellarWind]

I opened an account at Bodog, deposited with the usual 10% bonus (no longer available BTW), and played a little poker.

Later Bodog bought out Betholdem and received some more of my money in the process. They gave me the 10% bonus on this "deposit".

Since then I've played a little more but I am nowhere near clearing the bonuses. Right now I'm not playing at Bodog.

Can I withdraw some of my money without losing the bonus? I would be leaving all of the bonus plus some of my own money in the account.
