Binance started to have security problems. Some hackers with the help of API keys artificially increased the price of Viacoin and cashed out a lot of money. Japan has closed some exchanges, and in fact they are somehow connected with the Binance servers. Be careful!
How are the Japanese exchanges connected with the binance servers? You stated that this is FACT, where is this fact from?
I'm fairly certain that these are two stand alone events that just seemed to coincide..
Binance collected documents to obtain a license to trade in Japan. Therefore, these are related things. If you do not see any threat for yourself and you do not trade in Binance and do not keep your money there, you can not pay attention to these facts.
