最新报道:Bitcoin mining has reached unprecedented difficulty in 2025, with a record hash rate of 977 EH/s and soaring costs driven by high BTC prices. Large-scale farms using advanced ASICs dominate the sector, while innovators like Proto, led by Jack Dorsey, aim to revolutionize mining with open-source, modular rigs designed for longevity and efficiency. Proto's approach promises to reduce infrastructure expenses and support decentralization, though current rig availability remains limited.
