Bitcoin vs Ethereum: Core Differences in 2025
- Bitcoin: Proof-of-Work store of value. Halving cycles drive scarcity (21M cap). 2025 highlights: Spot ETF inflows ($50B+ YTD), Lightning Network for micropayments, and institutional adoption (e.g., nations like El Salvador holding BTC reserves).
- Ethereum: Proof-of-Stake platform for dApps, DeFi, NFTs. Upgrades like Dencun (2024) slashed Layer-2 fees; 2025 focuses on blobs and staking yields (4-6% APY). TVL: $120B+ in DeFi.
Bitcoin excels in security and simplicity; Ethereum in innovation and ecosystem (10K+ dApps).
