A shared set of rules
Bitcoin is a payment network whose participants verify transactions using shared rules. Under the current consensus rules, issuance declines over time toward a limit of 21 million bitcoin. A bitcoin can be divided into 100 million satoshis.
What makes the limit meaningful?
A number written in code is only part of the story. Network participants independently enforce the rules. Changing the supply policy would require people to accept different software rules; a single company cannot simply issue more bitcoin that existing nodes will accept.
The price is a separate question
A limited supply does not guarantee rising prices. Demand, liquidity, competition and confidence still matter. Bitcoin can experience severe drawdowns even while its issuance policy remains unchanged.
The question to keep asking
When you read a Bitcoin headline, separate three things: a change in the protocol, a change in access or regulation, and a change in market sentiment. They affect the investment case in different ways.
