Anyone having problems to do trading on their exchange ??.
Since several days it's not possible to trade, they claim that is is due to the transition of STAR

can you pls. indicate if trading is working with you ??
They won't respond to emails so that's already bad signal.
Some of coins on hitbtc are not able to deposit or withdraw and i heard also many complaints about losing coins and many more. Maybe don't hold your coins to that exchange if is not safe there try to find more safest exchange where you can trade your coins.
