I still remember in a year back of 2017 when I was new in trading at HitBTC exchange site. And this is the first trading exchange that I used at that time. So far, I never experience any difficulties and didn't face any troubles until I stopped and withdraw my fund earlier in the year of 2018. But now, I saw that HitBTC is plagued with complaints. So, my guess is better to stay away on this exchange.
yes, I also remember that. HitBTC used to be one of the recommended places to trade, it's just that now, there have been so many complaints that come, and most of it from withdrawing pending very long.
As far as I use HitBTC, I don't have any complaints other than the fee that is big enough for now. Well, I hope HitBTC can be like it used to be

Tremendous fee is the main reason why i leave this exchange.Its true that no exchange is 100% clean or safe from issues.Sooner or later there would be problems to pop out no matter how good the exchange is.The important thing is on how they do resolve it out and dont make the issue piled up and leave it unresolved.Lets take for example on how Binance is doing.
