Bitcoin halving is one of the most important events in the entire crypto world. It happens roughly every 4 years and has a direct impact on Bitcoin’s price and investor behavior.

What does halving actually mean?

Every 210,000 blocks (about 4 years), the reward miners receive for mining a new block is cut in half.

  • 2009–2012: 50 BTC per block

  • 2012–2016: 25 BTC

  • 2016–2020: 12.5 BTC

  • 2020–2024: 6.25 BTC

  • Since April 2024: 3.125 BTC

  • Next halving (~2028): 1.5625 BTC

This mechanism has been hard-coded into Bitcoin’s protocol from day one (designed by Satoshi Nakamoto in 2008).

Why does it exist?

It controls the issuance of new bitcoins. Total supply is capped at ~21 million BTC. Halving slows down how fast new coins enter circulation. Less new supply + same or growing demand = potential price pressure upward.

Historical price impact

  • 2012: ~$12 → ~$1,150 (following year)

  • 2016: ~$650 → ~$20,000 (end of 2017)

  • 2020: ~$8,700 → ~$69,000 (November 2021)

  • 2024: pre-halving ~$65–70k → new highs above $100,000 (late 2024 / early 2025)

Not every halving brings instant moon – macroeconomics, regulation, and sentiment always play a role. Long-term, though, halving is considered the strongest fundamental driver of bull markets.

What to expect after 2028?

The next halving is likely in March–April 2028 (block ~1,050,000), dropping the reward to 1.5625 BTC/block.

BTC inflation will already be extremely low (~0.4% annually), supply nearing the cap. Many analysts expect this to be the last halving with significant price impact – after that, the effect on bull cycles will weaken (new BTC issuance becomes negligible).

Price estimates post-2028 (various sources):

  • conservative: $150,000–300,000 (2028–2030)

  • optimistic: $300,000–500,000

  • extreme long-term: millions (with massive adoption)

Future price action will depend far more on institutional adoption (ETFs, corporate treasuries, nation-state reserves), regulation, and macro conditions than on halving itself.

One-sentence summary

Halving reduces the rate at which new bitcoins are created – less supply + same/growing demand = higher price (at least historically).
