@Jennifer Nelson.
Hi, I have been a victim of a scammer with the same nature of strategy in terms of what they offer (name of the company is SUPMiner). I am just wondering, did you manage to actually get your funds out? Also, did you manage to withdraw successfully in the past? Or this is the first time you are trying to withdraw and it did not work. Please feel free to reach out to me at jason.jumpcompany @ gmail.com so we can talk via email. I am also an investor of GDMining as well but not yet started with the big investment money yet. Thanks.
