Back vs. Edwards Clash: Miners' AI Shift Threat or Boost for Bitcoin at $77,921?

Bitcoin hits $77,921 (up 5.33%) as debate intensifies over public miners pivoting to AI, slashing BTC revenue share from ~90% to ~30% in 2-3 years. Hashrate has dropped to 870 EH/s from ~1 ZH/s peaks, with March mining difficulty down 7.76%; AI-focused firms soared ~500% in market cap while pure miners lagged. Charles Edwards flags network security risks from hash power exodus, but Adam Back argues it bolsters margins, cuts selling pressure, and supports prices—creating bullish short-term vs. long-term concern dynamics.
