What is the Bitcoin halving? Dates, rewards and why it matters
The Bitcoin halving cuts the reward miners receive for each block in half every 210,000 blocks, roughly every four years, slowing the creation of new bitcoin.
What a halving is
Bitcoin miners validate transactions and are paid in newly created bitcoin, called the block reward. Every 210,000 blocks the protocol cuts this reward in half. This is the halving.
It is written into Bitcoin's code, so no company or government can change the schedule on its own.
The schedule so far
A block is mined about every ten minutes, so 210,000 blocks take roughly four years. The reward began at 50 BTC in 2009 and has been halved several times:
2009: 50 BTC → 2012: 25 → 2016: 12.5 → 2020: 6.25 → 2024: 3.125
The 2024 halving reduced it to 3.125 BTC per block. The next halving is expected around 2028, when it should fall to about 1.5625 BTC. Because of these cuts, the total supply approaches 21 million coins, with the last coin expected around the year 2140.
Why it matters for price
A halving reduces the pace at which new coins enter the market. If demand stays the same while new supply falls, prices can come under upward pressure, which is why many investors watch these events.
Past cycles saw large rallies afterwards, but the sample is only a few events, and other factors such as interest rates, regulation and market sentiment also drive the price.
Risks and common mistakes
Because the date is known, the expected effect may already be priced in before it happens. Do not assume history will repeat; the price can fall after a halving too.
Lower rewards also squeeze miners' revenue, pushing less efficient miners out until fees and price adjust. Bitcoin stays highly volatile, so size positions carefully.
Frequently asked questions
When is the next Bitcoin halving?
It is expected around 2028, once the network reaches the next multiple of 210,000 blocks. The exact date depends on how fast blocks are mined.
What is the Bitcoin block reward after the 2024 halving?
3.125 BTC per block, down from 6.25 BTC before the April 2024 halving.
Does the halving always raise the price?
No. It cuts new supply on a fixed schedule, but price also depends on demand and the wider market, so there is no guaranteed effect.
