I don't think so. Binance is the best exchange all over the world and it's not easy to be hacked

. Also John McAfee tweeted that Binance downed because of hacking but I think he got paid to tweet like that to reduce faith of traders all over the world with this exchange. We just need to wait few more hours to see if Binance will really work again at 4 AM (UTC) or not.
John Mcafee is the lord of fake news on crypto he spread fuds so that he can earn with it and I don't think binance is been hack since their support are most likely alive maybe they are just doing some huge system update that's why we can see them up down for long hours but anytime soon they will surely came back again since they are earning good with this business and they will surely not turn down their traders easily.
