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.
