Free Ripples (or currency of your choice) in exchange for playing video on a loop
For those who want to get into cryptos but don't have as much money as they would like to invest, this gives you the opportunity to build a modest yet diverse cryptocurrency portfolio at no expense. You never know which will be the next one to hit $5,000.
What I do is go to Earn Ripple (or whatever) at the top left, and then Watch Videos. Load up a video or two, and let them run when you're asleep or not using the computer/s.
Tl;dr: Loop videos when you're not using the PC, and wake up to free cryptos.
