No One Controls Bitcoin
Bitcoin isn't managed by any one person or company. Instead, it's run by a network of computers (called nodes) spread across the world. These computers keep a record of all Bitcoin transactions.
Anyone can download free software to run their own Bitcoin node. Running a node lets you verify the rules of the network are being followed. The software is free and open source — transparent, with no hidden changes.
Mining for Security
Bitcoin mining is done by computers to secure the network. Miners use "proof of work" — computers put in lots of effort to create Bitcoin and confirm transactions. This process secures the entire system and prevents fraudulent transactions.
And unlike regular money, there's a cap to the amount of Bitcoin that can ever exist. This means it doesn't lose value like dollars because no one can cause inflation in the Bitcoin system.
Unchangeable Record
Once a transaction is recorded in the Bitcoin blockchain, it can't be altered or deleted. This creates a permanent and trustworthy history of all transactions.
Many computers across the globe collaborate to confirm transactions, secure the system, and maintain a reliable record. This collective approach ensures that Bitcoin remains independent and not under the control of any single entity.
