Cloud mining
Cloud mining is the process of cryptocurrency mining utilizing a remote data center with shared processing power. Cloud mining has been used by ransomware groups and scammers to launder cryptocurrency.
This type of cloud mining enables users to mine bitcoins or alternative cryptocurrencies without managing the hardware. The mining rigs are housed and maintained in a facility owned by mining company and the customer simply needs to register and purchase mining contracts or shares. Since cloud mining is provided as a service, there is generally some cost and this can result in lower returns for the miner.
