Cloud mining is a mechanism to mine a cryptocurrency, such as bitcoin, ETH, and LET using rented cloud computing power and without having to install and directly run the hardware and related software. Cloud mining firms allow people to open an account and remotely participate in the process of cryptocurrency mining for a basic cost, makes mining accessible to a wider number of people across the world. Since this form of mining is done via cloud, it reduces issues such as maintenance of equipment or direct energy costs. Cloud miners become participants in a mining pool, where users purchase a certain amount of "hash power." Each participant earns a pro-rata share of the profits in proportion to the amount of hashing power rented.
