Yes, i have a friend of mine who wanted to buy some Ethereum in there.. he deposited more than $1200 in his account, and a few hours later they didn't let him withdraw his money.
He sent a support ticket and it has never been answered
Just avoid this exchange, it is the worst one that has ever been created so far.
Do NOT TRUST HitBTC - they are running a massive Hit jobs on any account holders.
Coins deposit fine but getting coins out is an exercise in futility.
