Every ~4 years, Bitcoin's supply issuance is cut in half. The historical cycle that follows has been one of the most consistent patterns in crypto markets.
Bitcoin's code limits total supply to 21 million BTC. Every 210,000 blocks (~4 years), the mining reward is cut in half. This event is called the halving.
| Halving | Date | Price Before | Cycle Peak |
|---|---|---|---|
| 1st | Nov 2012 | ~$12 | ~$1,200 |
| 2nd | Jul 2016 | ~$650 | ~$20,000 |
| 3rd | May 2020 | ~$8,500 | ~$69,000 |
| 4th | Apr 2024 | ~$63,000 | TBD |
History doesn't repeat in crypto β but it rhymes loudly.
Past halvings occurred in very different market environments. Bitcoin's market cap is now much larger, making equivalent percentage gains harder. Never size a position based solely on cycle theory.
