Every exchange has already scammed a few of its customers, so there is no safe time to say: "This exchange is 100% safe".
I'd recommend trading/ withdrawing/ depositing in smaller amounts to avoid such issues, though the best thing you can do is go to their Headquarters if anything goes wrong.
something is very wrong with HitBTC. I withdrawed ~157k CDT Tokens and for over 4 days I see the yellow dots. The support is not answering at all . I was able to withdraw ENJ coins though.
What is very disapointing is the fact I can not even cancel the withdrawal. My money is just held and I am unable to react to the market. In the Telegram Channel from CoinDash there are several users who have the same issue.
I can not recommend HitBTC!!
HitBTC is one of the only exchanges where you don't need to verify ID to deposit, withdraw BTC or tokens in smaller accounts, ergo making this one of the most liked for these features.
Keep hitting support with your questions and try see if you can get anything out of them. Try live chat if they have it and don't be polite.
