Yeah, don't sign up with Binance just yet.  You wouldn't even be able to deposit any funds right now, because they've suspended deposits and withdrawals for all their customers, and there's no telling when everything is going to be back up and running.  They said it would take a week, and that was about a week ago.

I also would avoid Yobit, even though I've never had problems with them.  There have been too many complaints and scam accusations made against them for anyone to consider using them as their main exchange.  The good thing about them is that they offer a lot of coins, but their customer service is non-existent. 

Lately I've been buying NEO, and I've been doing it through Changelly.  Why?  Because exchanges like Poloniex and Bittrex now want KYC documents, and I don't want any exchange having my personal information.  If anyone knows of an exchange where I can buy NEO (and PIVX, which I'm also accumulating) without having to do KYC, please let me know.
