Each line is a price chart for a coin relative to its current value, starting from ~now (at the center line, orange to represent BTC) going back to August 14th, 2022.
So a few coins went up in value since August 14th, 2022 (as they started out below the orange line). But the vast majority went down in value (as they started out above the orange line).
I was pretty close, but there's now a much better chart.

That's a great way to generalize the ecosystem and I'm confident with just Bitcoin.
