Unlike traditional currencies, Bitcoin:

How Does Bitcoin Work?

Bitcoin runs on a technology called blockchain, which is a secure, public ledger that records every transaction.

1. Blockchain Technology

Every Bitcoin transaction is recorded in blocks and linked together in a chain. Once added, transactions cannot be changed or deleted, making Bitcoin highly secure.

2. Bitcoin Mining

Bitcoin transactions are verified by computers called miners. Miners:

• Validate transactions

• Secure the network

• Earn new Bitcoin as rewards

Mining also controls how new BTC enters circulation.

3. Bitcoin Wallets

To use Bitcoin, you need a digital wallet. Wallets store your private keys and allow you to:

• Send Bitcoin

• Receive Bitcoin

• Check your balance

Wallets can be mobile apps, hardware devices, or desktop software.

Bitcoin gives users control over their money, especially in regions with:

• High inflation

• Banking restrictions

• Currency instability

3. Global Payments

Bitcoin allows fast, borderless payments without relying on banks, making it ideal for international transactions.

In 2025, major companies, investment firms, and even governments are increasingly recognizing Bitcoin as a legitimate asset.
