Keep It Simple Stupid - also in Bitcoin.
I've drawn a triangle over the chart in D1 and a bigger triangle in W1. Using only the daily resp. weekly closing prices. And this triangle looks valid to me.
I've seen people drawing wedges or flags in the charts but the triangle is a more reliable chart pattern. So it may take a few days in the daily chart or 1-2 weeks in the weekly chart until this formation gets resolved but it will get resolved finally. ;)
And yes, it's more likely that symmetric triangles get broken to the upside. I think then we see 75k as the next stop.
