I'm not buying that the CFTC had anything to do with it, especially since the BTC price has been rather shaky in the upper USD 5000s in the first place. There might be a lot of reasons behind the latest drop, I doubt that yet another non-committing statement regarding ICOs is one of them.
Apart from that, I love this quote:
Bitcoin fell as much as 5.9 percent, its biggest loss in almost a month, to as low as $5,247.
I'm not sure whether to I'm more fascinated by the BTC price or by the fact that 6% drops have become newsworthy.
