Token withdrawal flat fee is a rip-off.I was happy with HitBTC for a while, APIs were OK, trading platform was easy to use. But withdrawing is very pricey, unless you have large amount to play with. I have withdrawn my BTC and ETH and costed me around $50. If I would have had $50,000 to play with, it would have been fine. But I had $500 to trade with and 10% of it is now HitBTC's. Use them if you have $50k+ to trade with. If you are just experimenting, like I did - be ready for the hefty "exit" fee.
