What Exchange would you recommend and why?
I use Binance, HitBTC.
Using HitBTC since the first trade so its kind of used to it exchanger. Having good interface and most of my coins are listed over there.
Binance being new has got even higher volumes for various coins and has over taken many big exchangers in short time. Plus one for their android application!
Any Exchange has give you problems or difficulty with to withdraw your money?
Yobit. Dont like it really due to their low volumes and lots of scam accusation. Also their support is worst of all.
