Cloud mining
Cloud mining is a method of mining in which users mine cryptocurrency on remote hardware. This model was born when the difficulty of mining increased to the point that it was difficult for miners to earn profit at home.
Cloud mining of cryptocurrencies can be done without major startup costs or technical knowledge.
Miners buy some portion of the hardware and mining power owned or hosted by cloud mining services or providers. The service providers choose the hardware settings, conduct maintenance, and choose their pool.
