October brought a wild mix of highs and lows for crypto miners. Bitcoin's hashrate just smashed through another ceiling, yet miner profitability? Crashed to unprecedented lows. Meanwhile, Malaysia's crackdown on power theft linked to mining operations exposed over $1.1 billion in stolen electricity—a staggering figure that highlights the darker side of the industry. On the corporate front, heavyweights like Bitdeer, Bitfury, Canaan, Marathon, Bitfarms, and TeraWulf aren't sitting still. These publicly traded miners and rig manufacturers are ramping up expansion strategies and hardware deployments. The hashrate surge continues to squeeze margins, pushing players to either scale aggressively or risk obsolescence. It's a brutal month that captures the paradox: more power, less profit.
