All of you are correct. The main problem of hitbtc is the withdrawal fee plus they like to pump some new coins as well.
Which may lead to big loss if you buy at the top.
Anytime I see exchanges rise the way hitbtc is rising, most especially exploiting others while rising. They are heading for a crash except they do enough to contrain themselves. The problem from inside the exchange organisation because of greed. People had been complaining on the exploit and nothing had been done. There are some coin still trading ICOs after getting on other exchanges. I hope it improve
