Phoneum is another cloud based mining app you run from your phone. It being cloud based means you don’t have to leave it running, so low battery consumption. They have different packages you can purchase to increase the mining rate and also offer referral rewards. Be sure to use the referral code wnuhxrhj to get 200 free PHM!
UPDATE 01/18/21: The currency is actually PHT. There are 5 games you can play to earn PHT, but by far the best is Crypto Cards and Crypto Connect 3. Crypto Treasures would be 3rd best. I have earned almost 200K PHT in a couple of months with the mining app and without spending very much time on the games (around $20 USD value).
