DOES MINING EVER STOPS?
At this moment, there are officially 4.000.000 people in PI Network.
If we grow to 10.000.000 or even100.000.000 , in worst case we are still at 40% of building the network,
so still at the beginning.
Just continue mining, and you will have a decent amount of Pi.
At a certain moment(according white page), -
date has not yet been determined-, when we arrive at phase 3, mining will stop.
