Fib levels and circles here show a potential retrace to earlier support at $215, less structural support seems to stand in the way at this point.
ETH is a hot iron due to issues of recent ICO craze induced network congestion, and Coinbase price plummeting briefly but extremely (to $13 from memory, great if you had a fishing line out ;).
This spook reverberates through investor's brains at this point it appears. Fair enough.
I'm reluctant to touch it if I can't hover over it like a hawk.
No trading advice, deploy due diligence in research.
In any event, happy trading.
