BTC hitting $5000 was always likely to trigger a correction.
China banning ICO's. And crypto purchase status seems to be uncertain in China as well.
Combine the two ...... perfect dump-storm. Expect it to go down more before it (hopefully soon) goes up again. And I'd imagine the recovery of some China based tokens may be slow to non-existent. Could even end up with a couple of completely dead ducks out of all this.
Fun times!
