Bitcoin hashrate decline nears 287 days; difficulty plunges nearly 20%; miner stocks surge on AI pivot, decoupling from BTC price

Bitcoin asset vs. miner equities decoupling. Production cost $78k vs $64k, but forced-selling appears exhausted. This is a key development for network security and miner behavior.
