Understanding the Core Differences
Bitcoin (BTC) and Ethereum (ETH) represent two fundamentally different approaches to blockchain technology:
- Bitcoin (2009): The original "digital gold" focused on scarcity (21M cap) and security through Proof-of-Work (PoW)
- Ethereum (2015): A "world computer" enabling smart contracts, DeFi, and dApps via Proof-of-Stake (PoS) since "The Merge"

Key Comparison Factors
1. Historical Foundations
- Bitcoin: Created as peer-to-peer electronic cash, evolved into institutional store-of-value
- Ethereum: Designed specifically for programmable contracts and decentralized applications
2. Monetary Policy
| Metric | Bitcoin | Ethereum |
|---|---|---|
| Supply Cap | 21M fixed | No hard cap (burn mechanism) |
| Current Inflation | <1% annually | ~0% post-merge |
| Last Halving | April 2024 | N/A |
3. Technical Performance
- Bitcoin: 10-minute blocks (~7 TPS), high security but limited scalability
- Ethereum: 12-15 second blocks (~30 TPS), enhanced by Layer-2 solutions like Arbitrum and Optimism
