Created in 2009, Bitcoin is a decentralized digital asset that enables peer-to-peer value transfers without reliance on banks or central authorities. As a purely digital currency, no physical bitcoins exist in circulation.
How Bitcoin is Created
Bitcoin enters circulation through a process called mining, where network participants (miners) validate transactions by solving complex cryptographic puzzles. Key aspects of mining include:
- Successful verification of transaction groups currently rewards miners with 6.25 BTC plus associated transaction fees
- Mining maintains network security through cryptographic rules that ensure stability
- All verified transactions are recorded on an immutable public ledger called the blockchain
Bitcoin Supply Facts
- Currently mined: ~19.5 million BTC
- Maximum supply: 21 million BTC (expected by 2140)
- Fixed supply makes Bitcoin inherently deflationary
