What is the halving?
Every 210,000 blocks —roughly every 4 years— the reward Bitcoin miners receive is cut in half. It has been written into the protocol since 2009: Bitcoin's monetary policy, predictable and non-negotiable. At the next halving the reward drops from 3.125 to 1.5625 BTC per block, slashing the daily issuance of new bitcoin overnight.
After the four previous halvings, Bitcoin went through bull phases peaking at all-time highs 12-18 months later — a suggestive pattern, but with only four observations it guarantees nothing about the future.
Halving history
| Halving | Date | Block | Reward |
|---|---|---|---|
| 1º | 28/11/2012 | 210,000 | 50 → 25 BTC |
| 2º | 09/07/2016 | 420,000 | 25 → 12.5 BTC |
| 3º | 11/05/2020 | 630,000 | 12.5 → 6.25 BTC |
| 4º | 20/04/2024 | 840,000 | 6.25 → 3.125 BTC |
| 5º | ~2028 | 1,050,000 | 3.125 → 1.5625 BTC |

Cycle phases: where we are
In the three completed cycles with data (2012, 2016, 2020), the top arrived between days 371 and 548 after the halving, and the bear-market bottom between days 777 and 924 (roughly 26-30 months later). The bar places the current moment within the ~4-year cycle that began in April 2024:

The objective data from previous cycles
| Cycle | Top (days) | Multiple* | Bottom (days) | Drawdown |
|---|---|---|---|---|
| 2012 | 371d (12/2013) | ×94 | 777d (01/2015) | −86% |
| 2016 | 526d (12/2017) | ×30 | 889d (12/2018) | −84% |
| 2020 | 548d (11/2021) | ×8 | 924d (11/2022) | −78% |
| 2024 | In progress — halving on 2024-04-20 at ~$63,850 | |||
* Multiple from the halving-day price to the cycle top. The series shows clear diminishing returns (×94 → ×30 → ×8) and softening drawdowns (−86% → −84% → −78%).
Cycle simulator
Adjust the two variables and the simulator projects the current cycle\u2019s top and bottom. The defaults extrapolate the diminishing-returns trend: each historical multiple was ~0.3× the previous one (×8 × 0.3 ≈ ×2.3), and each drawdown about 5 points milder.
Multiple over the halving-day price ($63,850): –
Historical: ×94 (2012) · ×30 (2016) · ×8 (2020). Trend extrapolation suggests ×2–×3.
Drawdown from top to bottom: –
Historical: −86% · −84% · −78%. The trend suggests −70/−75%.

Frequently asked questions
When is the next Bitcoin halving?
The fifth halving will occur at block 1,050,000, estimated around 2028. The exact date depends on the real pace of mining: this page recalculates it live from the current block height and the average 10-minute block time.
What happens at the next halving?
The block reward drops from 3.125 to 1.5625 BTC, halving the daily issuance of new bitcoin (from ~450 to ~225 BTC/day). It is Bitcoin's programmed monetary policy, in place since 2009.
How accurate is the countdown?
It is an estimate: blocks are mined every 10 minutes on average, but the real pace varies with hashrate. The page checks the real block height every 2 minutes and recalculates, so precision improves as the date approaches.
