Is there a way to see if a pool is at or near saturation point?
You have the info in Daedalus. Currently the saturation point is at 220~M.
If you need more information you have to check a site like : https://pooltool.io/
I thought the math showed it closer to 211 million. Unclear why Daedalus shows 220.
Probably it uses 33bn az total stake as you can see it in the end of the slider.
