oh no! i was using hitbtc this past few months. Now i am seeing many scam accusation. Hopefully you will resolve all of your issues or else this big exchange will turned into scam.
They are not scam at all, i have never used hitbtc as an exchange in order to trade bitcoin for any other crypto, but far as i know they are not 100% scam.
In fact, i traded some Dimcoins a few days ago for ETH and i succesfully withdrew them all to my eth address without any problems at all.
Maybe there is something wrong with this, they have a lot of issues right now, but they are still paying.
