Definition
The halving is one of Bitcoin’s most important economic mechanisms. By reducing the rate of new Bitcoin creation on a fixed schedule, it enforces digital scarcity. There will only ever be 21 million Bitcoin, and the halving ensures the supply approaches that limit asymptotically.
Halving history: 50 BTC (2009), 25 BTC (2012), 12.5 BTC (2016), 6.25 BTC (2020), 3.125 BTC (2024). The next halving is expected around 2028. Halvings historically have significant effects on mining profitability and market dynamics.
In Simple Terms
The event that cuts Bitcoin's block reward in half every four years, enforcing digital scarcity.
Halving is a term used in Bitcoin mining related to mining basics.
Also known as: Halvening, Bitcoin halving.

Understanding halving is important for Bitcoin miners because it directly impacts mining operations, hardware selection, or profitability calculations. Whether you are a home miner running a Bitaxe or operating a larger ASIC setup, this concept helps inform better mining decisions.
