What is a Bitcoin halving?

A Bitcoin halving is an event that occurs approximately every 4 years (every 210,000 blocks) where the block reward paid to miners is cut in half. This reduces the rate of new Bitcoin supply creation.

When is the next Bitcoin halving?

Bitcoin halvings occur every 210,000 blocks. The most recent halving was in April 2024, reducing the block reward to 3.125 BTC. The next halving is expected around 2028.

How many Bitcoin halvings have there been?

There have been 4 Bitcoin halvings: 2012 (50→25 BTC), 2016 (25→12.5 BTC), 2020 (12.5→6.25 BTC), and 2024 (6.25→3.125 BTC). There will be a total of 33 halvings until around 2140.

Bitcoin Halving Timeline

Every 210,000 blocks (~4 years), the number of new Bitcoin created per block is cut in half — a built-in scarcity mechanism that slowly reduces supply until the last satoshi is mined around 2140.

We are currently in the 4th halving era out of 33. That means only 12% of Bitcoin's monetary schedule has played out. If this feels late — it's not. Below are all 33 halvings mapped across Bitcoin's 131-year journey.

Why Halvings Matter

Predictable Scarcity

Unlike fiat currencies, Bitcoin's supply schedule is fixed in code. No central bank can change it.

Supply Shock

Each halving cuts new Bitcoin production by 50%, reducing sell pressure from miners while demand grows.

Historical Returns

Every past halving has been followed by a significant price increase within 12-18 months.
