最新报道:Bitcoin mining difficulty has surged to a record high ahead of the 2025 halving, compelling miners to increase computational power as block rewards diminish. Smaller miners face growing viability threats, potentially centralizing the network and undermining Bitcoin's decentralization ethos. The escalating hash rates, driven by advanced hardware, have reignited debates over energy consumption and environmental impact, despite increasing renewable energy usage. Analysts attribute the difficulty spikes to long-term trends, forecasting a post-halving landscape dominated by well-funded operators that could reshape the mining ecosystem.
