I've heard that Bitcoin has a limit of 21 million coins. I'm curious about what sets this specific cap on the number of Bitcoins that can exist. Is it a technical limitation or a design choice? What limits Bitcoin to 21 million?

In return for their efforts, miners are rewarded with new Bitcoin. However, as the reward diminishes, so does the supply of new coins.

Despite being a purely digital asset, Bitcoin's supply is strictly controlled by its embedded source code.

The code includes a mechanism known as halving, which reduces the rate of new Bitcoin creation over time.

Halving events occur periodically, cutting the reward for miners in half each time.
