What is the Bitcoin halving?
Bitcoin's protocol limits the total supply to 21 million BTC. To enforce this gradually, the reward paid to miners for adding a new block is cut in half approximately every 210,000 blocks - roughly every 4 years. This event is called the halving (or halvening). The most recent halving occurred in April 2024, reducing the block reward from 6.25 BTC to 3.125 BTC.
The halving matters because it directly reduces the daily issuance of new Bitcoin. Before the 2024 halving, approximately 900 new BTC entered the market every day. After the halving, that dropped to ~450 BTC/day. If demand stays constant or grows, this supply reduction creates upward price pressure - a mechanism that has played out in every prior cycle.
The 4 halvings - what happened each time
| Halving | Date | Reward | BTC at halving | Cycle top | Peak gain | Drawdown after top |
|---|---|---|---|---|---|---|
| #1 | Nov 2012 | 25 BTC | $12 | $1,150 (Dec 2013) | +9,483% | -86% |
| #2 | Jul 2016 | 12.5 BTC | $650 | $19,800 (Dec 2017) | +2,946% | -84% |
| #3 | May 2020 | 6.25 BTC | $8,500 | $69,000 (Nov 2021) | +711% | -77% |
| #4 | Apr 2024 | 3.125 BTC | $63,700 | - (current) | In progress | TBD |
The pattern is consistent, though the magnitude diminishes with each cycle as Bitcoin's market cap grows. The 2012 halving produced a 9,483% gain; the 2020 halving produced 711%. This diminishing-returns pattern is expected - it takes exponentially more capital to move a larger market. The bear markets that follow each top have also grown shallower - roughly -86%, -84%, then -77% across the three completed cycles - consistent with a maturing, less volatile asset.
The 4 post-halving phases
Each halving cycle moves through recognizable phases. The NHCI Score reflects where the market is within each phase in real time, combining on-chain data with market and macro signals.
Price typically consolidates near the halving price. Retail attention is low. On-chain shows long-term holders accumulating. NHCI Score: 35–50 range.
Price breaks above the previous ATH. Volume increases. MVRV rises. Media coverage returns. NHCI Score begins climbing into the 50–65 Bull zone.
Parabolic price action. NUPL above 0.75. aSOPR > 1.05. Fear & Greed at Extreme Greed for weeks. NHCI Score enters 65–75 Hot Zone or above.
Price peaks and enters multi-month decline. MVRV reverts below 1. NUPL drops toward 0 then negative. NHCI Score drops back toward the 0–35 Bottom zone - setting up for the next halving.
We are currently in the post-2024-halving window. The NHCI Score tracks 37 indicators in real time to tell you exactly which phase of the halving cycle Bitcoin is in - and whether the risk/reward is historically favorable.

The BTC NHCI Score does not use the halving date as a direct input. Instead, it reads the downstream effects of the halving through 37 on-chain, market, and macro indicators. When the halving begins compressing supply, it shows up in the data: long-term holder accumulation increases, exchange outflows rise, MVRV gradually climbs, and the NHCI Score reflects this shift in cycle positioning.
This approach makes the NHCI Score more robust than simple halving date calendars. It does not assume the cycle will peak at exactly 12 or 18 months - it reads the actual market conditions in real time. If the cycle extends (as cycles tend to do as the market matures), the NHCI Score will remain in the Bull zone longer. If conditions deteriorate early, the score will show that too.

Key takeaways
- Bitcoin halving occurs every ~210,000 blocks (~4 years), cutting miner rewards in half
- All 4 halvings have been followed by a major bull market within 12–18 months
- Gains per cycle: 2012 (+9,483%), 2016 (+2,946%), 2020 (+711%) - diminishing but still significant
- The 2024 halving (April 2024) reduced daily issuance from ~900 to ~450 BTC/day
- The NHCI Score tracks the halving cycle's effects through 37 real-time indicators - not by calendar
I have lived through three halvings, and the lesson rhymes even when the numbers do not. Each one tightened new supply and a bull market followed within 12 to 18 months - but the returns shrank every cycle, and the drawdowns in between were deep enough to shake out most believers. I read the halving as a tailwind, never a timer. I stay long the thesis and let the on-chain data, not the calendar, tell me when a cycle is running hot.
Frequently asked questions
What is a Bitcoin halving?
A Bitcoin halving is a programmed event that occurs every 210,000 blocks (approximately every 4 years) that cuts the block reward miners receive in half. Bitcoin halvings reduce the rate of new supply entering the market, creating a supply shock that has historically preceded major bull markets.
When was the last Bitcoin halving?
The fourth Bitcoin halving occurred on April 19, 2024, reducing the block reward from 6.25 BTC to 3.125 BTC. The next halving is expected around 2028, when the reward will drop to approximately 1.5625 BTC.
How does a Bitcoin halving affect price?
Every Bitcoin halving has been followed by a major bull market within 12–18 months. The 2012 halving preceded an 8,000% rally; the 2016 halving preceded a 3,000% rally; the 2020 halving preceded a 700% rally. The mechanism is supply: fewer new BTC entering circulation means existing demand creates more price pressure.
How many Bitcoin halvings have happened?
As of 2024, four Bitcoin halvings have occurred: the first in November 2012 (50→25 BTC reward), the second in July 2016 (25→12.5 BTC), the third in May 2020 (12.5→6.25 BTC), and the fourth in April 2024 (6.25→3.125 BTC). Bitcoin will have 32 halvings total before all 21 million coins are mined around 2140.
Is the Bitcoin halving cycle reliable for investing?
The halving provides a structural tailwind but does not guarantee bull markets or their timing. On-chain indicators like MVRV, NUPL, and the NeverHodl NHCI Score are more precise tools for identifying where exactly in the cycle Bitcoin is. The halving sets the backdrop; on-chain data shows current positioning.
