Yes hitbtc is a scam. my money suddenly dissapeared with no one to talk to.
I believe you should post some evidence. I used HitBTC and all the transactions are successful. The only problem that I have was the transfer of DNT that took 20 hours but it still pushed through
They are at least continually upgrading wallet software of the not so much traded coins, been LSK recently, frozen some funds during that time.
Since there are no deposit/withdraw limits you can utilize their service for small batches. On a same trust level I would range yobit and some consorts.
