US Bitcoin ETFs attracted $197M last week — the first positive result after two months of outflows. We examine the key details and market implications.
Where the Money Flowed
Top inflow recipients:

| BlackRock (IBIT) | $67M | +0.9% AUM |

Investor Strategies Revealed
Flow analysis shows two distinct approaches:
- Conservative players favor IBIT (BlackRock) for its tight 0.01-0.03% spreads

Geographic Breakdown
Brokerage reports indicate:
- 65% from North American pension funds
- 22% from Asian hedge funds (mainly Singapore/Hong Kong)

5 Reasons for the Turnaround

Deep Dive: Catalyst Analysis
GBTC's fee reduction narrowed its gap with IBIT from 0.8% to 0.3%. Bitcoin's rebound from $56,500 triggered FOMO sentiment. Institutions are rebalancing portfolios to show crypto exposure ahead of quarterly reports.
Funds are deploying "buy the dip" strategies, especially given historical post-halving rallies. Glassnode data shows 78% of large investors increase crypto allocations during 15%+ corrections.
