I’ve recently downloaded an application that lets you mine crypto by the name of PI which is being worked on by a few ph students in Stanford. You can mine on your phone apparently with little to no battery drainage. I’ve dug into this a bit and decided to download it. I’ll post the website if anyone is interested to check it out. Use the invite code (Tally). https://minepi.com/
Here is a Reddit thread about the crypto as well… let me know your thoughts
