# #$BTC Coin
Bitcoin (BTC) is the first and most well-known cryptocurrency, created in 2009 by an anonymous individual or group known as Satoshi Nakamoto. It operates on a decentralized network, using blockchain technology to securely record transactions.
Here are a few key points about Bitcoin:
Blockchain Technology: Bitcoin transactions are recorded on a public ledger called the blockchain. This ensures transparency, security, and immutability, meaning once a transaction is confirmed, it cannot be altered or reversed.
Decentralized: Bitcoin is not controlled by any central authority (like a government or bank). Instead, it's maintained by a global network of nodes (computers) that validate transactions and secure the network.
Limited Supply: There will only ever be 21 million Bitcoins, making it a deflationary asset. This limited supply is one of the reasons Bitcoin is often compared to gold as a store of value.
Mining: New Bitcoins are introduced into the system through a process called mining, where participants solve complex mathematical problems to validate transactions and secure the network. Miners are rewarded with newly minted Bitcoin for their efforts.
Volatility: Bitcoin is known for its price volatility. The value of Bitcoin can fluctuate dramatically within short periods, making it a speculative investment for many.
Use Cases: Bitcoin is used for various purposes, including a store of value, a medium of exchange (though adoption as a regular currency is still limited), and as a hedge against inflation in some regions.
Security: Bitcoin's security comes from its decentralized nature and the cryptographic algorithms used to protect transactions. However, it’s important to store Bitcoin safely, as losing access to a wallet means losing access to the coins.
