What Is Bitcoin (BTC)?
Bitcoin (BTC) is the world’s first decentralized digital currency, introduced in a 2008 whitepaper by the pseudonymous creator Satoshi Nakamoto. Launched in January 2009, Bitcoin operates on a peer-to-peer (P2P) network, enabling direct transactions without intermediaries like banks.
Key Features:
– Decentralization: No central authority controls Bitcoin.
– Peer-to-Peer Transactions: Users transact directly, reducing fees and delays.
– Limited Supply: Capped at 21 million coins, ensuring scarcity.

Founders of Bitcoin
The identity of Satoshi Nakamoto remains unknown, though several individuals have been speculated as potential creators. Nakamoto’s vision was to create a “trustless” financial system where transactions are verified by network consensus (via proof-of-work) rather than centralized institutions.
What Makes Bitcoin Unique?
- First-Mover Advantage: Bitcoin pioneered blockchain technology.
- Security: Its SHA-256 cryptographic algorithm protects against fraud.
- Global Adoption: Accepted by merchants, investors, and institutions worldwide.
Bitcoin’s Circulating Supply
As of 2024, over 19.5 million BTC are in circulation, with the final coin expected to be mined by 2140. New coins enter circulation through mining—a process where miners solve complex puzzles to validate transactions.
| Metric | Detail |
|---|---|
| Total Supply | 21 million BTC (hard cap) |
| Current Supply | ~19.5 million BTC |
| Inflation Rate | Decreases with each halving event (every 4 years) |
How Is the Bitcoin Network Secured?
