He is probably referring to the shitload of fud that was thrown at Binance after their lengthy maintenance phase. People kept spreading fud and whatnot, and that while prior to that Binance has always worked fine, and that without many problems, which is indeed a good point. McAfee, the clown has also been part of the fud attack against Binance during their maintenance phase, and that while he knew that they were just performing maintenance. From all the crippled exchanges in this market, Binance fits in the top five exchanges that are seemingly the least crippled.
The only thing that worries me though, is that they have managed to grow insanely fast in such a short period of time. Sure, Chinese exchanges shutting down may have largely contributed to that, but I can't really figure out what it is that makes people flow into Binance aside from that. Exchanges as Bitstamp have a long track record of being a reliable platform, but that's something we can't yet conclude when it comes to Binance. In that regard, it will be interesting to see how they handle further growth in the coming months/years.
For now I think Binanace is good it offered a pretty nice exchange with good coin support. From my opinion because they had their own ICO helped them to boost their exchange plus those affiliate links wich are cheap trick to boost up your product and let others talk about it. I like them because they have pretty high limit for not verified users like 2BTC per day, but I do not like the fact that you collect dust from trading some small amounts on their exchange. But yes they are pretty new and have successed to attract public attention as I said it might have to do with their affiliate links as people started to put them around the internet. The fact is you don't really have any big altcoin exchange you can trust much at least from my opinion.
