Market Structure: Breadth and Momentum Diverge
The market capitalization expanded $77.7 billion to $2.70 trillion, a 2.97% two-day gain, while 24-hour volume climbed 41.3% to $103.9 billion. This volume surge paired with market-cap growth suggests broad-based accumulation rather than concentrated rallies. Bitcoin dominance rose modestly from 59.07% to 59.22%—a 15 basis point move—indicating BTC is marginally outpacing altcoin gains but not dramatically reasserting leadership.
Ethereum dominance held nearly flat, declining 3 basis points from 11.093% to 11.067%, suggesting the largest altcoin is treading water relative to the broader market. The stability in both BTC and ETH dominance despite the overall market rally indicates that gains are distributed across the full asset spectrum, a hallmark of healthy bull-phase momentum rather than defensive consolidation into mega-cap names.
Sentiment and Capital Allocation: Greed Surges, DeFi Follows
The Fear & Greed Index surged 11 points in a single 6-hour window (Sept 3, 17:00 UTC to Sept 4, 00:00 UTC), jumping from 65 to 74, and has remained at that elevated level for the past 20 hours. This sharp pivot into 'Greed' territory—the highest reading in the 48-hour window—signals a marked shift from cautious to aggressive investor behavior. The sustained plateau at 74 suggests the sentiment move was not a fleeting spike but a structural repricing of risk appetite.
