There are several alternatives without so many problems.
Any suggestions? I'm becoming annoyed by finex too. Thinking about moving to OKCoin.
it depends where you from, how you want to trade high leverage futures or just simple spot.
OKCoin.com in general is a good place for everything despite the FUD attacks we had in the community at some point.
If one is leaving Bitfinex because of lag/engine problems, Okcoin leaves much to be desired. Funny how exchange fiascos come as flavors of the month. Last month, it was Okcoin, after the DDOS fuckery that left many, many traders unable to connect and instantly margin called. No compensation for hardly anyone. Not to mention its utter lack of professionalism (exhibited by the Star/Roger Ver episode). Ever taken a look at their corporate structure? Shady as hell. It's highly questionable that their "proof of reserves" audit was legit -- their former CTO said that it was gamed by Okcoin. Allegations of naked maker bots trading against (and stop running) their users.
No thanks.
