Too many factors have coincided (keyword: "coincided") with very, very FUDdish news, which have been the catalyst of the fire ignited by the complete moron doing the Goxed coins to pay creditors.
So what happened is:
1) Noobs go to bitcoinwisdom
2) Noobs see big candle starting because of the dumping of Goxcoins
3) Noobs panic and google "Bitcoin news"
4) Noobs see the SEC news, see the Binance hack news, see the MtGox news... the spiral to FUDland begins and it's just a domino effect of selling
Once we are past all the noobs selling and all the Goxcoins sold, we will go back to 20k+ because as we've seen, the only reason we didn't keep growing was thanks to the stupid person in charge of the Goxcoins sold it on Kraken instead of OTC as anyone that isn't a complete clueless idiot or someone that doesn't want to damage the market price would do (and I think this was a plan to do just that).
