I also like qTrade, is a smooth an flawless exchange. Had no problem with them so far.
It's buggy as f... If i choose next trading pair and then trade history it shows me trade history from previous trading pair - i had to reload page. It does not always update recent trades/order book - i have to reload. It loads slow and sometimes does not load full content - i have to reload. After checking few trading pairs, reloading page few times to load full content i sometimes hit rate-limit. But it does not change the fact that it is my second best exchange. It's honest, no fake trades, innovative coins - they are not listing tones of recently popular shitcoins (like ADA or NEO), 0 maker fees
Idena network update:

Looks like we are accelerating again.
