Cloud mining of Bitcoin is a process where individuals or companies rent computing power from remote data centers to mine Bitcoin. Instead of setting up and maintaining their own hardware, they pay for a share of the mining power and receive a portion of the mined Bitcoin in return. It’s a way for those interested in mining to participate without the need for extensive technical knowledge or the upfront costs of purchasing and managing mining equipment. However, it’s important to be cautious, as there have been instances of scams in the cloud mining space.
