7starcoin has a powerful network of HPM-750 powered Peta hash super speed computers specifically designed to mine Bitcoins at the minimum time and resource. The power those machines generate is used to solve blocks which in turn will reward you with Bitcoins. The power generated to be able to mine Bitcoins is called “Hashing Power”. We sell hashing power in the form of Bitcoin mining contracts. The more GH/s you purchase the more Bitcoins you will be able to mine.
