5. *Transparent:* All transactions are publicly recorded on the blockchain.
*How Does Bitcoin Work?*
1. *Mining:* New Bitcoins are created through a process called mining, which involves solving complex mathematical problems.
2. *Transactions:* Users send and receive Bitcoins using unique addresses.
3. *Blockchain:* Transactions are verified and recorded on the blockchain.
*Advantages:*
1. *Financial Freedom:* Bitcoin provides an alternative to traditional fiat currencies.
