If you are still mining this coin from your smartphone, probably it's the time to remove the app permanently.
Mining Pi Network on smartphone when you turn off your phone is still possible. I can not step in shoes of people who believe in that technology used for Pi Network. It is unrealistic if we are not greedy. Don't need to have deep knowledge too, just not being greedy.
Like you can earn money on your phone when you sleep and your phone is sleep (power is off) too. If I was those people who believed in Pi Network, when I was introduced about that coin like that, I will stop listening.
Pi Network does not have a blockchain too.
Hilarious that some exchanges tried to use the name Pi Network to scam their users by listing a scam token with a name Pi Network months ago.
