Don't use Hitbtc, never, really. In every time many people said that hitbtc is a scam, but now a lot off traders shared on reddit that theirs account were blocked.
Mine account too. Support ticket is - #264376
Support team asks impossible things:
1) my Monero wallet data (i don't know which one, i have only private key and i won't give it them)
2) They told that they want to contact with service which i use, i told them 3 times that i use my own wallet with my private key. They don't read it and just repeat the template phrase.
10 days they've kept my money. And there are many traders with the same issues.
i have verified account on bifinex, kraken, wex, bittrex, binance. I sent to them my document and photo and it was enough for them.
Hitbtc wasting time and every time clarifying something new. They don't read messages in ticket, they just send templates phrases.
