BlackRock digital assets head Robert Mitchnick said Bitcoin and Ethereum remain the only two cryptocurrencies attracting meaningful investor demand.
Summary
- BlackRock says Bitcoin and Ethereum dominate investor demand.
- IBIT saw $26B inflows in 2025 despite Bitcoin’s price decline.
- ETH staking ETF aims to add yield to ether exposure.
This comes as the asset manager evaluates future ETF products. Speaking on CNBC following the launch of BlackRock’s ETHB staked ether ETF, Mitchnick stated Bitcoin commands approximately 60% of crypto market share while Ethereum holds the low teens.
The comments come as BlackRock’s IBIT Bitcoin ETF recorded $26 billion in inflows during 2025 despite Bitcoin falling nearly 50% from its October all-time high.
IBIT ranked fourth globally for ETF inflows last year, becoming the only product in the top 20 to post positive flows while delivering negative price returns.
Year-to-date flows for IBIT remain slightly positive, with approximately 90% of the investor base maintaining steady accumulation patterns through the drawdown.
Bitcoin and Ethereum dominate investor allocation decisions
Mitchnick described Bitcoin as a “digital gold emerging monetary alternative” while calling Ethereum as “a technology centric bet around blockchain innovation and the various use cases of ether and digital assets.”
The distinction decides how investors approach portfolio allocations, with Ethereum exposure aligning more closely with technology and venture equity allocations.
BlackRock’s ETHA became the third-fastest ETF in history to reach $10 billion in assets under management, trailing only IBIT and Fidelity’s FBTC.
The newly launched ETHB adds staking yield to spot ether exposure, addressing what Mitchnick called a “limitation” in original ether ETF products that lacked yield capture mechanisms.
The staking feature makes ETHB “much closer, like the Bitcoin ETPs were, to a silver bullet for a lot of investors in terms of a super convenient exposure vehicle,” Mitchnick said.
Long-term investors drive Bitcoin and Ethereum ETF flows
Retail investors and financial advisors comprise the majority of ETF demand, with both segments showing opportunistic buying during price declines.
Hedge funds account for roughly 10% of flows, primarily running basis trades that go long ETFs while shorting futures contracts. These trades remain neutral for Bitcoin’s price but create flow volatility when basis spreads compress.
Mitchnick noted BlackRock sees “pockets of interest” in other crypto assets but maintains a “discerning approach” to product expansion.
The firm continues evaluating assets as liquidity, scale, and use cases develop, but Bitcoin and Ethereum remain where investor interest concentrates overwhelmingly.
