Play video on a loop when you're not using the PC, and in exchange receive cryptocurrency of your choice
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 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.
Let me know if you have questions and I will do my best to help.
Tl;dr: put videos on a loop while you're asleep -- wake up to cryptocurrencies.
