Crypto mining is the process of validating transactions and securing blockchain networks through computational power. Bitcoin miners use ASIC machines, while Ethereum’s transition to proof-of-stake (PoS) shifted mining efforts to staking pools and validator nodes. Mining profitability depends on block rewards, mining difficulty, and energy efficiency. The industry explores eco-friendly mining solutions, solar-powered mining farms, and decentralized mining pools to reduce environmental impact. Investors track hash rates, mining rewards, and GPU availability to assess mining opportunities across various blockchain networks.
