Maybe China is one of many reasons for the latest dump when The Chinese government continues to implement measures to prohibit cryptocurrencies but it doesn't have to be the biggest reason. As far as i know the reason of the latest dump because there are rumors that Binance exchange site was hacked, this make investors feel fear. Moreover, "Nobuaki Kobayashi" Bitcoins Tokyo Whale Sold $400 Million and Hes Not Done Yet. Maybe this biggest reason made the price of bitcoin dump.
