#signdigitalsovereigninfra $SIGN Bitcoin (BTC) is the first decentralized, peer-to-peer digital currency, launched in 2009 by the anonymous Satoshi Nakamoto. It operates without central banks or authorities, using blockchain technology and cryptography (SHA-256) to secure transactions. With a capped supply of 21 million, it is highly volatile and often used as a speculative asset.

Here are key aspects of Bitcoin:

How it Works: Transactions are bundled into blocks, verified by miners, and added to a public, immutable ledger known as the blockchain.

Purpose: Primarily used as a store of value ("digital gold") and a peer-to-peer payment method.

Security & Privacy: Transactions are public and traceable, but not explicitly anonymous, as user identities are linked to alphanumeric addresses, not names.

Divisibility: Each Bitcoin is divisible into 100 million smaller units known as "Satoshis".

Limits: The supply is hard-capped at 21 million coins, with new coins generated through a, energetic mining process that reduces over time.

Volatility & Risk: Bitcoin is considered a high-risk investment due to its significant price fluctuations, having experienced sharp rallies to over $70,000 and steep, rapid declines.
