EFast EFree is a simple android app, which let's you earn Ethereum for watching a short ad.
One video gives you between 5-200 points. For withdrawal one needs a coinbase account, and 5.000 point. The withdrawal is processed instantly, and is worth around 0.04$

Tip for passiv-earn: Use a program that allows automatic taping, and a 'back/return' button. Look in the play store.

Would appriciate using my ref-code "1KPS2" :)
