Bitcoin (BTC) is a decentralized digital currency that allows for peer-to-peer transactions without the need for intermediaries like banks. It was created in 2009 by an anonymous individual or group using the pseudonym Satoshi Nakamoto.
Here's a simplified explanation:
*Key Characteristics:*

3. *Limited Supply*: The total supply of Bitcoin is capped at 21 million.
4. *Blockchain*: Bitcoin transactions are recorded on a public ledger called the blockchain.
*How it Works:*
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.
3. *Decentralization*: Bitcoin operates independently of central banks and governments.
4. *Limited Inflation*: The capped supply of Bitcoin helps prevent inflation.
*Disadvantages:*
1. *Volatility*: Bitcoin's value can fluctuate rapidly.
2. *Regulatory Uncertainty*: Bitcoin's legal status varies across countries.
3. *Security Risks*: Users must secure their wallets and transactions to prevent theft.
