Bitcoin is digital money that is open to all and controlled by no one. It operates on fixed rules enforced through cryptography and secured by computing power. Unlike traditional currencies, Bitcoin’s security and issuance are backed by energy through a process called proof-of-work, making it resistant to manipulation. Running on the world’s most decentralized and secure monetary network, Bitcoin enforces a fixed supply and allows anyone to store and transfer value without permission. It works because participants voluntarily follow its rules, creating a system that minimizes trust and remains highly resilient.
