Imagine a building under construction with a set number of bricks—21 million. Every four years, the number of workers laying bricks gets cut in half. At first, progress is quick with lots of workers. But over time, fewer workers mean fewer bricks laid, and eventually, no more are added. That’s Bitcoin. Its supply is capped at 21 million, and the process of halving ensures it becomes scarcer over time, like finishing a masterpiece with limited materials.
