As you can see on the chart, we've had 2 big bear flags and the've played out exactly the same, both went down. Take a look at the ellipses drawn on the chart. For both bear flags they've played out exactly the same (until now) and will probably follow along for the last drop. Do it think it's over after that? No, probably not. 5K target is still active. I think from here it will probably follow the ellipsis and go a bit sideways from there and than making one last drop to about $5000-5100 with a maximum low of $4800.
5K seems to be one of the strongest support lines and one of the largest psychological barriers for Bitcoin. 5K is about a 75% retracement which should be enough correction to make newer highs in the future. Also after such a long down trend, there must be an upside movement.
