Bitcoin (BTC) is the first decentralized cryptocurrency, introduced in a 2008 whitepaper by the pseudonymous Satoshi Nakamoto and launched in January 2009. It operates on a peer-to-peer network without a central authority.
How It Works
Bitcoin uses a proof-of-work consensus mechanism where miners compete to solve complex mathematical puzzles to validate transactions and add new blocks to the blockchain. This process secures the network and creates new bitcoins as block rewards.
Key Properties
Limited Supply: Only 21 million bitcoins will ever exist, making it a deflationary asset.
Halving: Approximately every four years, the block reward is cut in half, reducing the rate of new supply entering the market.
Decentralization: No single entity controls the Bitcoin network — it's maintained by thousands of nodes worldwide.
Bitcoin as Digital Gold
Bitcoin is often referred to as "digital gold" due to its scarcity, durability, and role as a store of value. Many investors view it as a hedge against inflation and currency devaluation.
