If the immediate lower trendline is broken, then any of the fibs levels on the chart, may be the levels to look for.
I don't see it falling lower than at max $6500 at the current moment, but it may of course reverse before that.
Seems like there is an SHS in the play as well:
With the SHS in mind, I would assume that BTC might just rebound then touching the SHS neckline (red line). That area has very strong support (pink color line), so it might be the turning point.
