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.
Hitbtc is a big site and has a lot of users. But lately I've heard a lot of comments complaining about their transactional regime, high fees and transaction errors that often happen. This is a bad signal for all traders.
I think you should recommend to Hitbtc management and quickly switch to Binance to avoid property loss.
