Key Metrics:
The explosive growth of January-February has given way to a more measured pace. This isn't necessarily bearish—it suggests the market is maturing from speculative inflows to buy-and-hold behavior.
Dominant Player: BlackRock's IBIT captured ~78% of institutional flows, cementing its position as the preferred vehicle for Bitcoin exposure.
Notable: Capital is rotating toward tokenized treasuries, with $12.8B allocated across various protocols. Institutions appear to be diversifying within the crypto ecosystem rather than exiting.
NVIDIA (NVDA) Institutional Metrics:
