Every four years, the amount of new Bitcoin entering circulation gets cut in half. Every time it has happened, what followed changed everything.
The Halving: Bitcoin’s Built In Supply Shock
Every 210,000 blocks, roughly every four years, Bitcoin’s mining reward is cut in half. This is called the halving. It is hardcoded into Bitcoin’s protocol and cannot be changed by anyone. In 2009 miners earned 50 BTC per block. In 2024 that dropped to 3.125 BTC.
This matters because Bitcoin’s price is driven by supply and demand. When the supply of new coins entering the market gets cut by 50%, but demand stays the same or increases, price pressure builds. Every previous halving has preceded a massive bull run within 12 to 18 months.
The 2024 halving has already happened. If history repeats, the most explosive part of this cycle is directly ahead.
The Historical Pattern
| Halving | Date | Price at Halving | Cycle Peak | Return |
|---|---|---|---|---|
| 1st | Nov 2012 | $12 | $1,100 | +9,000% |
| 2nd | Jul 2016 | $650 | $19,700 | +2,930% |
| 3rd | May 2020 | $8,600 | $69,000 | +702% |
| 4th | Apr 2024 | $64,000 | TBD | In progress |
The pattern is not guaranteed. Past performance does not guarantee future results. But the supply dynamics are mechanical. Fewer new coins are produced every day while demand from institutions, ETFs, and individuals continues to grow.
The Two Year Window
This is why we call it the two year fork. After each halving, there is roughly a 12 to 24 month window where Bitcoin tends to move aggressively to the upside. After the 2012 halving, Bitcoin ran from $12 to over $1,100. After 2016, from $650 to nearly $20,000. After 2020, from $8,600 to $69,000.
The 2024 halving occurred in April. That puts the projected cycle peak somewhere between late 2025 and mid 2026. This window does not last forever. The time to position is before the move, not after it.
This is also why the timing of purchasing mining hardware matters. Miners bought before or during the early stages of a bull run benefit from both the rising Bitcoin price and the declining cost basis of production.
What This Means for Miners
If you start mining now, you are producing Bitcoin during what has historically been the most profitable phase of the cycle. The reward per block is smaller, but the value of each coin is climbing.
Miners win twice in this phase: the Bitcoin they produce appreciates in value, and the machines they own also increase in resale value as demand for hashrate grows. This dual return is unique to mining and does not exist when you simply buy Bitcoin on an exchange.
The fork in the road is here. You either position before the move, or you watch it happen from the sidelines.

Frequently Asked Questions
What is the Bitcoin halving?
The halving is a programmed event that cuts the Bitcoin mining reward in half every 210,000 blocks, approximately every four years. It reduces the rate of new Bitcoin creation, creating a supply shock that has historically preceded major price increases.
When is the next Bitcoin halving?
The most recent halving occurred in April 2024, reducing the block reward to 3.125 BTC. The next halving is expected around 2028, when the reward will drop to 1.5625 BTC per block.
Does the halving always lead to a price increase?
Historically, every halving has been followed by a significant price increase within 12 to 18 months. However, past patterns do not guarantee future results. The supply dynamics are mechanical, but price also depends on demand, macro conditions, and market sentiment.
How does the halving affect miners?
The halving cuts mining revenue per block in half. Miners with high electricity costs may become unprofitable. Efficient miners with low power costs continue to profit, and if Bitcoin’s price rises as it has after previous halvings, mining becomes very profitable despite the reduced block reward.
