My preferred exchanges, though any exchange besides Yobit seems decent right now would have to be (hope you guys don't mind ref URLs to certain exchanges, plus using a ref helps me to help you, it is a win-win):
Binance: (Ref URL: https://www.binance.com/?ref=10173292)
Bittrex: https://www.bittrex.com/ (No Ref program, even though they are a major exchange, cheap buggers)
Cryptopia: (Ref URL: https://www.cryptopia.co.nz/Register?referrer=Gherik)
HitBTC: (Ref URL: https://hitbtc.com/?ref_id=5a6b2b994b66f)
Kucoin: https://www.kucoin.com/ (Ref program ended) =(
Stocks.Exchange: https://stocks.exchange/ (no ref program)
That's all the exchanges I can think of for now. There is liqui, but for some reason, liqui is being stupid, and I can't login. Friend also told me liqui has been doing shady stuff, so may start steering clear of liqui as well.
In any case, hope to see Veggie listed soon! Will be making my own post on cryptocurrencytalk forums about Veggie to get the word out. =)
Thanks for the suggestions, I think this is a pretty good list and we'll definitely be applying to some of those exchanges
