Bitcoin rose above $64,000, making it the only major cryptocurrency in the source to post gains during a broader market decline that hit Ethereum, XRP, and other large tokens. At the same time, public Bitcoin mining companies cut their hashrate (the computing power securing the network) by 21% over nine months, signaling a shift in strategy as listed miners look beyond a pure expansion of mining capacity. The combination highlights Bitcoin's relative strength in a weak market and changing economics for miners, whose business models are often shaped by power costs, hardware efficiency, and post-halving revenue pressure.
