I've been in this market for a long time. I never had a serious investment in HitBtc. HitBtc is obviously a questionable exchange. Always be cautious about such exchanges.
I have been using hitbtc for every trading. And it is unusual that my withdrawal is not being process for a week. It is the answer on that, that it needs a kyc. I have been trusting this exchange for a long time and now many issues occur that it could be a scam. Hope that my coins there wont lose.
