Today dumped the price "unexpected" because many people changed from bearish to bullish after last breakout and close above 4000 $. And that's the reason why the big players dumped the market ;). From chart technical view this was a perfect Elliot wave which finished at point 5 and should be followed by an ABC correction.
Expect further price decreases in the next days if the price break down from up trend channel.
-wait for another good long entry at 3650 $
-shorting from here is not worth after this dump today
