That is an interesting chart! I think it it will serve people well to remember that outsized moves in bitcoin happen seem to happen in both directions. Which was the point of the post.
It's easy to say when we are at 1200 that we'll go back to 200 before we go back up, and feel confident that the correction to 200 is natural and the subsequent rise is inevitable because how else will it capture x% of global remittance (which is the 'success' endgame scenario) and usurp broken currencies. To do this, it will have to grow exponentially in terms of market cap (and hence price).
When we are actually at 200 its much harder to maintain that belief!
