I had to leave for the technical issues they're facing right now because of their premature release of the
new website.
BTC Withdrawal worked. Took 6 hours, but with the outflow of liquidity right now I expected this delay.
Also, I personally had never a problem withdrawing or depositing. Sometimes delays at extraordinary peaks.
In my opinion: no scam. But they lack professionality.
I will come back to them as soon they get it straight.
