They have developed a Free Bitcoin Cloud Mining server. Don't expect high earnings, it is a combination of the faucet and cloud mining concepts, like a game. Users start with 20 GHs SHA-256 cloud mining as a starting bonus and can earn bitcoins proportional to their GHs amount ike a classic cloud mining server. GHs can be purchased with bitcoins and bonus points which can be earned for every login. Interestingly, They give opportunity to hack other users' account and thus users can steal 10% of the victim's GHs. Users can change their mining policy at anytime. For example, choosing "Cheaper GHs" will decrease GHs price with 20%, therefore choosing this strategy will be wise before purchasing GHs. They are not expecting high revenues from this project, it is an experimental free bitcoin cloud mining project. revenue items: 1. We bought a cloud mining from a known company. We've donated its income to this project. 2. Advertisements 3. Donations LINK ----> bitzfree.com/?ref=YbkN0nLiWhzpdrCNejcX2BibbntFwfbXe5l
