This is ONE way this might play out.
First requirement is that BTC is currently forming a bull flag (pink pattern).
If it does, the target of the bull flag would be the same as the target of the previous falling wedge (yellow), around $9800-10.000.
From there, the large bear flag (blue), that by now would have taken shape, would take BTC down to 5K territory.
It looks nice! But a lot of charts here look nice and never play out, so don't take this as financial advice!
