What is Bitcoin Halving?

Bitcoin halving is an event that happens every four years where the reward for mining new blocks is cut in half. This reduces the rate at which new bitcoins are created, making Bitcoin more scarce over time.

The most recent halving occurred on April 19, 2024, reducing the block reward from 6.25 BTC to 3.125 BTC.

Why Halving Matters

Halving directly affects Bitcoin supply. Before halving, 6.25 new BTC were created every 10 minutes. After halving, only 3.125 BTC are created. This 50% reduction in new supply, combined with constant or increasing demand, historically leads to price appreciation.

Historical Performance After Halvings

  • 2012 Halving: BTC went from $12 to $1,100 in 12 months (9,000% gain)
  • 2016 Halving: BTC went from $650 to $20,000 in 18 months (3,000% gain)
  • 2020 Halving: BTC went from $8,700 to $69,000 in 12 months (700% gain)
  • 2024 Halving: BTC was at $64,000 at halving, reached $100,000+ by December 2024

2024 Halving: What Actually Happened

The 2024 halving was different because Bitcoin had already reached new all-time highs before the event. ETF approval in January 2024 drove massive institutional demand. Post-halving, BTC continued its rally, crossing $100,000 for the first time in December 2024.

What to Expect in 2025-2026

Historically, the 12-18 months after halving see the strongest gains. If the pattern holds, we could see BTC reach $150,000-$200,000 by late 2025. However, past performance does not guarantee future results.

How to Trade the Halving Cycle

  • Accumulation phase: Buy during the 12 months before halving
  • Markup phase: Hold during the 12-18 months after halving
  • Distribution phase: Take profits near the cycle peak

Miner Economics Post-Halving

The April 2024 halving cut the block subsidy from 6.25 BTC to 3.125 BTC, instantly halving newly minted supply while existing hash rate stayed. The consequence played out in the miners' dashboard:

  • Marginal producers running on older ASICs and power above cheap wholesale rates flipped to cash-burn or exited, measurable as a hash rate dip and higher difficulty reset in the quarter after halving.
  • Revenue per hash collapsed roughly in half at constant prices, forcing fees-from-activity to carry a bigger slice of miner income.
  • Hash ribbon (the 30-day/60-day hashrate spread) flattened in the months after, the classic shedding-of-incompetent-capital signal.

The Hash Ribbon as a Gauge

The hash ribbon matters because mining economics are the market's physical register:

  • When the 30-day average hash rate crosses below the 60-day, miners capitulate and selling pressure spikes; a ribbon flip often marks local bottoms.
  • Buyers who enter when hashrate is climbing back through the 60-day are buying into recovering production economics, not into a falling knife.

In the post-2024 cycle, the ribbon never flashed the deep capitulation of previous halvings, which told holders the market was absorbing the subsidy cut without a miners' distress sale.

Stock-to-Flow and Why It Failed the 2021 Test

The halving narrative loves stock-to-flow (supply divided by annual issuance), which predicted explosive price-to-flow mapping. The 2021-2024 experience broke the direct wiring:

  • S2F mapped scarcity to price linearly, but the actual market spent 2021-2023 in the 15k-70k band, far below its backtest fantasy.
  • Institutional flows (ETF approval early 2024, growing corporate treasuries) diluted the pure supply mechanic as a price driver.
  • The model survived as a long-horizon anchor (halvings structure supply), not as a price oracle, and traders who date its pronouncements learned to discount it.

What the 2024 Cycle Actually Showed

Keep the receipts: after the April 2024 halving, price first chopped, then trended through record territory toward 70k+ into late 2024 and into 2025's ETF-fueled highs.

  • The halving's gift was structural: it removed daily sell pressure of ~450 BTC (roughly half of the 900 BTC/day pre-halving subsidy) in a regime where ETF demand was new and growing.
  • Volatility after the halving stayed elevated by stock-market standards but calmed versus the 2016 and 2020 cycles, evidence of more mature participants.

The 2028 Preview

The next halving (projected April 2028) cuts the subsidy to 1.5625 BTC. Three expectations with real logic:

  1. The subsidy's share of new supply contracts below half of today's, so macro flows and fee markets weigh heavier in price setting; halvings become slower drivers.
  2. Miners with power economics, not hardware vintage, hold the marginal exit column every time the subsidy halves.
  3. Position sizing and timing should target the structural years (subsidy cut plus ETF demand) rather than the halving day itself, because day-of moves since 2020 have been noise, while the year-after has repeatedly carried the trend.

Halvings matter because they change the ledger's physics, not because the calendar date itself is a signal. Read the miner dashboard, watch the ribbon and the ETF flows, and treat the halving as infrastructure tax reform, not a guaranteed date to buy.
