It's basically the Blockchain is flooded by an unconfirmed transaction, This strange thing happened right after some shit news regarding Co-Founder of Bitcoin.com decided to sold his BTC and buy BCH. This is obvious that there is a group behind it that spreading the FUD to dump BTC. This may what they called "Operation Dragon Slayer". But don't worry once they realize that crypto market will be dump as well, They will shitting BTC again. Expect new ATM after this Big crash. Keep on Hodling or Bag some cheap BTC! 
So did he or did he not sell his BTC? I immediately called bullshit on that, but I have received no confirmation whatsoever from any other source. FUD is IMO real, people want to buy at a low price.
