In 2025, crypto mining profitability remains viable but tighter post-Bitcoin halving, with rewards at 3.125 BTC and production costs ~$106K vs. BTC price ~$102K. Success hinges on cheap renewable energy, efficient ASICs, and altcoins like ETC or Monero. Miners earned $11.2B globally, up 7.1% YoY, though margins are slim for small ops. Adaptability key.
