A crypto halving is an event where the reward for creating new blocks is cut in half. The most famous example is the Bitcoin halving.
Why halvings happen
Bitcoin was designed with a limited supply and a reward schedule. Every halving reduces the number of new BTC created per block, slowing new supply over time.
Does halving raise price?
A halving can affect supply, miner economics, and market expectations, but it does not guarantee a price increase. Markets often price in expected events before they happen.
Halvings are important because they show how a blockchain monetary policy can be coded into the network rules.
