This is what it says on Chainmine.io website:
Unlike paper money, Bitcoin and other cryptocurrencies are generated mathematically. Our cloud miners provide the computing power needed to generate new Bitcoins and secure the Bitcoin network. Bitcoins are not managed by any central government or banks that decide the future of the system. The Bitcoin system offers freedom. Freedom that we want to make available and easily accessible to everyone. Today, Bitcoin is the most secure computer network on the planet, almost impenetrable! The reason for this is hash power.
