Bitcoin (BTC) is the original decentralized digital currency, created in 2009 by an anonymous entity named Satoshi Nakamoto. It operates on a blockchain, a distributed public ledger, eliminating the need for central authorities like banks.
Bitcoin's key features include its finite supply (capped at 21 million coins), making it deflationary, and its peer-to-peer transaction capability. While initially envisioned as a payment system, it's increasingly seen as "digital gold" – a store of value. Its price is highly volatile, influenced by market demand, institutional adoption (like ETFs), and macroeconomic factors. As of June 7, 2025, Bitcoin's price fluctuates around ₹92,00,000 INR, with a significant market capitalization.
