I've got a bit of bitcoin stuck on a site called crex dot exchange. They have a .1 BTC verification fee and I was wondering if anyone knew answers to the following questions:
1. Is the site safe/not a scam, and would I be ok to verify on there for a trading account?
2. If I'm able to get the BTC off of there without verifying, or is it stuck only to that website's members until I verify?
3. If there is a way to get a hold of a verified account to transfer that BTC over to it, and then transfer it to my preferred wallet?

I've tried to make payments to my other wallets and it doesn't seem to work. I've also tried making a secure deal on their website (a feature I don't know much about) but it never got approved. Anyways if anyone has detailed info about how crex works and if there are any safe options for me to move this BTC I'd be happy to hear it.

Thanks for your time.
