What happened to these projects?

I was scrolling through Gemini just checking out some random projects that I’ve seen around for a while but never really looked in to when two of them caught my eye. What I saw was absolutely shocking.

The first project was Yearn.Finance or YFI. The price as the time was $6,223 or so. I scrolled down to see what it’s all time high was and I could not believe when I saw that its ATH was $90,787.00. That’s about a 93% crash.

The next was ZCash or ZEC. That project is currently at $37.70 with an ATH of $3,191.93.

What happened to these projects? Are they likely to zero out? That is an absolutely insane price drop. I feel for those of you who are tangled up in projects like that.
