it seems btc can't hold the 16k resisdence . Then it had to be down at least h1*0,8 => 3500* 0,8 = 2800 ~3000
it saw 11500 ( panic sell ) .
Now double bottle again 13000 which head is 16000.
if trend not going to upward then it should be down at least h2*0,8 = 2400$ .
13000-2400=~11600$ support zone.
also with wide bottom left and side, 19 head - 13 bottom....
