Market Expansion and Sentiment Inflection
The crypto market added approximately $60.2 billion in total market cap over the 48-hour window, growing from $2.633T to $2.693T. This 2.3% expansion occurred alongside a material shift in market sentiment: the Fear & Greed Index jumped from 65 ('Greed') to 73 ('Greed'), marking the most significant single move in the period. The sentiment inflection occurred between September 3 at 21:00 UTC and September 4 at 04:00 UTC, suggesting a catalyst-driven repricing rather than gradual drift.
Trading volume accelerated to $96.5B from $74.3B—a 29.8% increase—indicating that the market expansion was accompanied by genuine participation rather than passive price appreciation alone. The elevated volume-to-cap ratio and sustained 70+ Fear & Greed reading suggest market participants are actively repositioning into risk assets.
Dominance Structure: Bitcoin Steady, Ethereum Flat
Bitcoin dominance edged up marginally from 59.06% to 59.19%—a 13 basis point gain—signaling no significant rotation away from the largest asset despite broad market strength. Ethereum dominance remained essentially flat, declining 20 basis points from 11.10% to 11.08%, indicating the two largest assets captured gains proportionally to the broader market rather than diverging in investor preference.
