Bitcoin's third “halving”, the programmed event where mining rewards drop, has occurred, lowering the payout to 6.25 BTC per block; the last halving was in 2016
Bitcoin's third halving, the network's quadrennial landmark and the most anticipated event this year in the cryptocurrency industry, has finally happened.
Context & Ripple Effects
This is the second act of a pattern the coverage has tracked for years: after experts debated how the 2016 halving would hit prices and miners, the network has now executed the same programmed 50% reward cut on schedule, dropping the payout to 6.25 BTC per block.
The timing matters because the stress test just ran on a smaller chain — Bitcoin Cash's own halving a month earlier pushed many miners' gross margins to near zero — giving a live preview of what a subsidy squeeze does to marginal operators.
First-order effects
- Miners validating blocks see their subsidy revenue cut in half overnight, from 12.5 to 6.25 BTC, while their power and hardware costs stay fixed — the exact margin compression Bitcoin Cash miners just experienced.
Second-order effects
- Higher-cost mining operations become unprofitable first, pushing hashrate offline or toward the cheapest-power operators; the 2021 coverage showing bitcoin's hashrate nearly halving within weeks of a price drop illustrates how quickly capacity exits when unit economics break.
Third-order effects
- The pattern holds on schedule: four years later the fourth halving cuts the subsidy again to 3.125 BTC, confirming that each cycle structurally culls inefficient miners and concentrates the industry around low-cost power and industrial scale.
The trend: Bitcoin's fixed issuance schedule turns every four years into a forced consolidation event for the mining industry, with each halving shifting share toward the lowest-cost operators.
