There is news that Japanese authorities have suspended two exchanges. But no reason to worry. The suspensions are due to weak security at those exchanges. It's not a "ban crypto" move -- but an "if you are dealing with people's assets, provide some proper security or get banned" move.
The SEC news are being misreported and it has been implied the MtGox $400mm sell-off happened today, additionally, news about Japanese authorities cracking down on unethical exchanges and the Binance "hack" happened at the same time -- leading to the current dump. However, after a closer look, none of that news are net negatives for crypto and the FUD is due to the media modifying the message to fit their sales models.
