Bitcoin (BTC) spot ETFs recorded $88.04 million in total net inflows on Feb. 20, with BlackRock's IBIT accounting for nearly three-quarters of that figure.
Ethereum (ETH) spot ETFs, by contrast, drew just $17,200 combined a fraction of Bitcoin's haul.
The disparity highlights a persistent gap in institutional appetite between the two largest crypto assets by market cap.
What Happened
BlackRock's IBIT pulled $64.46 million in a single session, pushing its cumulative historical net inflows to $61.303 billion.
No other Bitcoin ETF came close on the day.
On the Ethereum side, BlackRock's ETHA led with $1.78 million in net inflows, lifting its cumulative total to $11.875 billion. The remaining Ethereum ETFs collectively saw negligible or flat flows.

Why It Matters
IBIT's dominance is not a one-day anomaly. The fund has consistently attracted the bulk of Bitcoin ETF flows since the products launched in January 2024, cementing BlackRock's position as the de facto gateway for institutional Bitcoin exposure.
The Ethereum ETF category, approved in May 2024, has yet to generate comparable momentum. The $17,200 net inflow figure on Feb. 20 illustrates how thin demand remains outside of ETHA on most trading days.
The gap between Bitcoin and Ethereum institutional flows continues to widen, raising questions about whether Ethereum ETFs will ever close the structural deficit - or whether Bitcoin retains a durable first-mover advantage with institutional allocators.
