$BTC Bitcoin (BTC) – 150 Words

Bitcoin (BTC) is the world’s first and most well-known cryptocurrency, created in 2009 by the pseudonymous developer Satoshi Nakamoto. It operates on a decentralized, peer-to-peer network without a central authority or bank. Bitcoin transactions are verified by network nodes through cryptography and recorded on a public ledger called the blockchain.

The key innovation of Bitcoin is its limited supply—only 21 million BTC will ever exist—making it deflationary by design. It uses a proof-of-work consensus mechanism, where miners compete to solve complex mathematical puzzles to validate transactions and earn new bitcoins as rewards.

Often described as "digital gold," Bitcoin is increasingly viewed as a store of value and hedge against inflation. While it is volatile, Bitcoin has gained institutional interest and global adoption over time. It can be used for peer-to-peer payments, held as an investment, or integrated into financial services through crypto infrastructure.
