Yep it's clear that someone wanted to deliberatly fork the chain and dump on exchange to cash BTC out.
Some people will lose if the exchange don't/didn't block transfers out/markets.
This is my first front row seat of an actual fork attack... it's ugly

What we bought right now was just hotair?!!!
The coin will disappear when fork recover?
WTF!!!
Wasn't even hot air..... hope you didn't spend much......
