Digital Generation, also known as Coingeneration has just released their website and program that builds upon getting people to share their computer performance with them to build a super computer. They pay you per "thread" you support them with, and a single computer with average specs (i5 CPU and ~8gb ram) can handle tens of threads at a time. Currently I'm running their program on my computer with a couple of threads, and I'm using less than 5% of my computer's CPU.
The first thread is completely free, which in this case means that you can register http://coingeneration.com/auth/new/599399/
, run the program and earn 1$ a day (30$ a month) without doing anything at all, completely auto-pilot, and at the same time use your computer as normal. You can ofcourse purchase more threads to earn a lot more, but this will cost you a few bucks. If you're sceptical about this, simply register and earn the 1$ a day, every day.
