Market Structure: Modest Cap Growth Amid Stable Dominance
The total crypto market capitalization increased $48.05 billion from $2.655T to $2.703T over the 48-hour window, representing 1.8% growth. This expansion occurred on stable daily volumes averaging $78.3 billion, indicating that new capital entered without unusual volatility spikes.
Bitcoin dominance edged down slightly from 59.13% to 59.01%, a 12 basis point contraction that falls within noise. Ethereum dominance similarly held flat at 11.05%, remaining virtually unchanged at -6 basis points. This structural stability suggests the market cap gains were distributed broadly rather than concentrating into mega-cap assets, though neither BTC nor ETH materially lost relative position.
