I came across this coin project called pi. Apparently it's mined through your phone and there's 10m people so far.
I mined a few coins, if anyone wants to check it out I can invite you but it's invite only. Go to
www.minepi.com/Walkingstiff make sure you use thf invite code Walkingstiff
I know this, on their first launched I downloaded Pi via playstore in the android, then it mined I stayed active on it for a couple of months it was actually close to 1 year I think 10 months, then suddenly I got bored and found out that they are just hyping their community. Also, none of the mobile phone can able to mine, if ever their is, it is still impossible. Therefore, this is just really a waste of time.
