OK so I found an interesting crypto called bee.com, could never be anything but the cost of entry is basically zero.

You download the app, use a referee code, here's mine if you want it "failingforward" and hit mine every 24 hours. It then mines away in the cloud for 24 hours and reminds you to hit mine again.

The rewards will drop as more people sign up and they have grown to 4 mil in 4 months so there is a bit of momentum.

Will it be anything? Who knows? What does it cost? A click every 24 hours then shut down the app.
