i moved my alt coins to bittrex and cryptopia.poloniex is a very slow site and i cant log in from my mobile.
then main thing is always maintain and missed lot of trades because of that .sorry good buy poloniex .
Do you agree with me ??
Depends which coin you are trading, not all altcoins in mobile behave slowly, I tried ripple and it's extremely slow and freezes the screen.
In bittrex is much faster and I have started to like this exchange even though I haven't used it for a long time.
Also poloniex withdrawal time takes a lot, but in bittrex it's pretty fast, the deposit is not fast at all (for bitcoin deposits)
