What is Bitcoin?
Bitcoin (BTC) is a decentralized digital currency introduced in 2008 by the pseudonymous Satoshi Nakamoto. Operating on peer-to-peer (P2P) technology, it eliminates the need for central banking authorities through:
- Distributed ledger (blockchain) verification
- Cryptographic security for transactions
- Fixed supply cap of 21 million coins
- Programmatic issuance via mining
Unlike fiat currencies, Bitcoin derives value from:
- Mathematical scarcity
- Network consensus
- Immutable transaction records
How to Acquire Bitcoin
Mining (Computational Verification)
- Early adopters mined BTC using consumer CPUs/GPUs
Current requirements:
- 56.48 EH/s network hash rate (as of 2019 data)
- 7.41T mining difficulty
- 0.00003394 BTC/T/day yield
Mining pools now dominate due to:
- Collective hash power combining
- Proportional reward distribution
- Consistent payout structures
Purchasing BTC
- Cryptocurrency exchanges (spot markets)
- Peer-to-peer (P2P) platforms
- BTC ATMs (physical locations)
