Really I'm very upset with this exchange... They have one of the most expensive withdrawal fees I've ever see... I saw this kind of abusive fees in other exchanges like yobit but I tought HITBTC will be a little more serious due to the fact its great volume... They don't need to charge those abusive fees... Really... If they doesn't change their politics I think I will withdraw all my fund from there (despite the fact they will thieve me in every withdrawal I'll make) 
I think latoken is far more expensive when it comes to withdrawal fees are ranging 4.50$ to 5$. in hitbit the withdrawal fee of xrp is 1.12$ in latoken its 4.90$ for me hitbtc is still cheap (cheap but not in btc withdrawal)
