Buddy, that's not actual mining that people do on their phones using apps that mine for them in the background or even when the app is closed if they click a button once every 24 hours, just like how PI and its app used to work, or still works, maybe. Those apps are basically just assigning you a certain amount of tokens or coins every 24 hours based on how many people you have invited, etc. By the end of their so-called mining period, they generate the tokens or coins that all their users have mined through their TGE, and then distribute them accordingly. If the token gets listed, and tends to get a good market value, you might earn something from it, otherwise, you just wasted your time with it.

The point is, you are not mining anything with those apps, they've just used the word mining to attract more people, or make it sound cool or something.
