1. *Mining*: New Bitcoins are created through a process called mining, which involves solving complex mathematical equations.
2. *Transactions*: Users send Bitcoins to each other using unique addresses.
3. *Verification*: Transactions are verified by nodes on the network, ensuring the integrity of the blockchain.
4. *Wallets*: Users store their Bitcoins in digital wallets, which can be accessed through software or hardware.
*Advantages:*
1. *Security*: Bitcoin transactions are secure and irreversible.
2. *Anonymity*: Users can make transactions without revealing their identities.
