I have now made two withdrawal requests from GP. And, after the 10 day (!) processing time, I was notified that my withdrawal request has been "randomly selected" for further review. This review process takes 30 days, and after that I can re-request. Being randomly selected twice, huh?
Note, the amounts I am attempting to withdraw are not large- less than $500usd. I have now emailed the company twice, once to my "account manager" and have had no communication.
What GP is doing, then, is common thievery. They'll gladly take your deposited funds and make incentives to offer you imaginary money on top of your deposited funds. I call the money imaginary, the winnings imaginary, because the only REAL transaction has been my original deposit disappearing from my REAL bank account.
I'd be so happy to alter my experience with them, when they take any sort of action. So far, nothing.
