Bitcoin works differently from traditional money and banking. These three basic ideas will help you understand what makes it different.
Fixed Supply
Decentralized Network
Cryptographic Security
Bitcoin has a maximum supply of 21 million coins. This limit is built into the system and is one of the key differences between Bitcoin and traditional currencies.
Bitcoin operates on a worldwide network of computers rather than being controlled by a single bank or company. The network works together to verify and record transactions.
Bitcoin uses advanced cryptography to help secure transactions and ownership. Your private keys are especially important because they control access to your Bitcoin.
Understanding Self-Custody
Self-custody means taking personal control of your cryptocurrency instead of leaving it with an exchange or other third party. It also means taking responsibility for protecting the keys that provide access to your digital assets.

Bitcoin Has a Fixed Supply
Bitcoin was designed with a maximum supply of 21 million coins. New Bitcoin enters circulation according to rules built into the network, making its supply predictable and limited.
What About Other Cryptocurrencies?
Bitcoin is only one type of cryptocurrency. Thousands of other digital assets exist, each with different purposes, features, supply rules, and levels of risk. Understanding those differences is an important part of learning about crypto.
