Instead of looking for an exchange with low withdrawal fee I would suggest to consider a reputed exchange. You do not end up again like Cryptopia. Although I am not ignoring the fact that legal hazard can happen with any exchange.
It's always safer to keep your crypto in your own wallet.
I echo this suggestion, you should choose a better and reputable exchange rather than looking for those exchange that has lower fees that than usual exchange that you have used.
Well, I haven't used them but good luck using them and wishing you that everything's going to be good there. The fee seems to be low 0.2% and for bitcoin it is 0.00006404 which is fairly low.
