General projection of how GBTC (and thereby BTC) will bottom.

Updated
This is loosely how I think BTC could bottom as depicted in the GBTC ETF. The 1.54 support line I drew corresponds with the 1200 ATH of the 2013 bull cycle. (The correspondence isn't 1.2 GBTC -> 1200 BTC because GBTC has a premium associated with it.)

I'm not suggesting I have the exact touch points marked of what the price action will be within a declining broadening wedge, but I expect the pattern is going to be that, a declining broadening wedge.
