Bitcoin’s rise from an obscure digital asset to the heart of Wall Street has had an unlikely backer: Larry Fink, the BlackRock CEO who eventually came around to Bitcoin’s promise — and its enormously lucrative potential.
The Observer recently traced Fink’s seven-year evolution, from calling Bitcoin “an index of money laundering” in 2017 to recognizing its “digital gold” characteristics years later, just before his firm turned Bitcoin into one of its fastest-growing investment products.
Of course, Bitcoin has a long history of winning over its critics.

Even Michael Saylor, the Bitcoin bull who transformed Strategy, formerly MicroStrategy, into the world’s largest corporate Bitcoin holder, was once a skeptic. In 2013, Saylor famously declared that Bitcoin’s “days are numbered.” Today, Strategy holds more than 845,000 BTC on its balance sheet, according to BitcoinTreasuries.NET.
For Fink, the epiphany may have been driven partly by Bitcoin’s appeal as a “debasement trade” — a scarce asset investors can turn to when they’re worried about currencies losing purchasing power. But the business opportunity was impossible to ignore.
In January 2024, the U.S. Securities and Exchange Commission approved BlackRock’s iShares Bitcoin Trust (IBIT) alongside 10 other spot Bitcoin ETFs, giving investors a regulated and familiar way to gain direct exposure to Bitcoin’s price without having to buy or custody the cryptocurrency themselves.
Then IBIT started breaking records.
As CoinDesk reported, the fund reached $70 billion in assets in just 341 trading days, making it BlackRock’s biggest fee-generating ETF. When Bitcoin surged above $126,000 last October, IBIT briefly approached $100 billion in assets, reaching that threshold five times faster than any ETF in history, according to Bloomberg.
Wall Street access doesn’t eliminate Bitcoin risk
While IBIT made it easier for investors to gain exposure to Bitcoin — and helped broaden its appeal beyond crypto’s traditional base — it didn’t insulate them from the asset’s notoriously volatile swings.
That became painfully clear this year. By June, Bitcoin had fallen below $60,000, marking a roughly 53% decline from its October peak.
The selloff also tested investors’ appetite for Bitcoin ETFs. U.S. spot Bitcoin funds suffered a record eight consecutive weeks of net outflows between May and early July, shedding roughly $8.3 billion over that stretch, according to SoSoValue data analyzed by The Block.
The waters have steadied somewhat since then, with Bitcoin reclaiming $80,000 after a powerful rebound that began in August.
The rally gained momentum after the Treasury announced it would at least double buybacks of longer-dated government debt, a move that helped ease pressure on bond yields and boosted risk assets. Around the same time, President Donald Trump hosted crypto and finance executives at the White House, where he urged Congress to pass a “fair version” of the crypto-focused CLARITY Act.
But the rebound doesn’t erase what came before. ETF investors have learned that wrapping Bitcoin in a familiar Wall Street product doesn’t make its sharp swings disappear.
BlackRock’s answer to that volatility isn’t to avoid Bitcoin altogether, but to size the exposure accordingly.

How much Bitcoin belongs in a portfolio?
In 2024, BlackRock suggested that a 1% to 2% Bitcoin allocation could be reasonable for investors who believe the asset will become more widely adopted and are willing to accept the risks that come with its volatility. Its analysis put Bitcoin in roughly the same risk-budgeting range as the “Magnificent Seven” technology stocks in a traditional 60/40 portfolio.
Fink has also contemplated what larger institutional allocations could mean for Bitcoin’s price. During the 2025 World Economic Forum in Davos, Switzerland, he said he had discussed with a sovereign wealth fund whether it should allocate 2% or 5% of its portfolio to Bitcoin. If allocations of that size became widespread among institutional investors, Fink said Bitcoin could eventually reach as high as $700,000, according to MarketWatch.
Others in the industry have made a similar case for modest but concentrated crypto exposure. Vanessa Grellet, managing partner at Arche Capital, told a Grayscale Investments conference earlier this year that a 1% to 5% allocation to Bitcoin or Ether has historically improved risk-adjusted returns in a traditional 60/40 portfolio, aided by crypto’s correlation characteristics.
“The institutional momentum around digital assets is undeniable,” Grellet said, pointing to spot ETF flows, corporate treasury allocations and growing interest from sovereign wealth funds.
