Although not related to Bitcoin, these services are similar to mining the digital currency. Instead of using computer power to mine Bitcoins, you sell your idle processor power to companies like these, who sell it to other companies and institutions who use it to solve complex tasks. It is like turning everyone's computer into a supercomputer.
MQL5 Cloud Network is another network which you sell your idle CPU power to for credits, which you exchange for money. Rather than running a program, with this network you simply set up services that run in the background. This one is currently live and earning credits.
Coinbeez is another company which will pay you for sharing your processing power. It is also very new but doesn't have its app available yet. You can still register and build your downline while waiting for them to release their software.
There are three membership levels: Regular, Co-Founder, and Founder. Higher membership levels allow you more earnings from your referrals and you can buy more workers.
Update! The application is available for download and ready to earn!
