Difficulty Adjustment

Each chain balances responsiveness against stability. Bitcoin's two-week epoch is slow but predictable, capped at 4x per adjustment. Bitcoin Cash's ASERT responds every block against an exponential baseline, neutralising the hashrate oscillation attacks of its early years. Kaspa and Monero adjust continuously.

Adjustment events are tradable information for miners: a large downward adjustment (like Bitcoin's June 2026 drop amid the AI pivot) immediately raises every remaining miner's revenue — old hardware briefly comes back to life until hashrate returns.
