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 stopped using this phone mining project because mining it means I have to surrender my privacy because they will have access to my devices and obviously they are a centralized project the positive things they have done is introducing Cryptocurrency to their miners who have no idea what Cryptocurrency is, but they will eventually lead tot he truth about Cryptocurrency because they are likely to explore the technology further.
