that is just my thought....i am not a PRO ;)
1. Is the real mass market sentiment that BTC will crash?
2. Is the perception that its just a correction and will gain in future?
Market structure shows a strong bottom but until we hold below your blue line convincingly then no downside with be created. After all, the BTC market is in one of the biggest bull runs in history, so why would you considering shorting?
Try to trade the chart and not your own thoughts, because it might not be what the mass market believes.
If you can anticipate others in the market, you will be successful.
In terms of my TA itself, I was concerned particularly about the validity of the lower line, and perhaps I should be starting from an earlier point which might give better correlation with the various low points? Perhaps somewhere around the beginning of December perhaps?
