A Fixed Supply

There will only ever be twenty-one million Bitcoin. This limit is part of Bitcoin's rules, set by its creator, Satoshi Nakamoto. No government or company can print more. That scarcity is why some people compare Bitcoin to digital gold.

How New Coins Appear

New coins are created only as rewards to miners for adding blocks. Every two hundred ten thousand blocks, about four years, that reward is cut in half. So new supply keeps shrinking over time. The last tiny fraction of a Bitcoin is expected to be mined around the year twenty one forty.

What It Means

About ninety-five percent of all Bitcoin has already been mined. Each Bitcoin splits into one hundred million sats, so you can own a small piece. Changing the limit would need almost the whole network to agree, which is very unlikely. A fixed supply does not guarantee any price. This video is not investment advice.
