BlackRockâs head of crypto, Robbie Mitchnick, says the gravitational center of Bitcoinâs market structure has shifted decisively from miner issuance to exchange-traded fund demandâand thatâs why classic four-year âhalving cyclesâ should command far less attention than they used to. In a Bankless interview released November 10, Mitchnick argued that the ETF era is now the dominant flow regime for BTC, even as leverage and short-term derivatives noise continue to whipsaw prices.
âItâs not over,â Mitchnick said when asked whether the latest sell-off marked the end of Bitcoinâs current cycle. âThis is the fifth cycle weâve seen [âŚ] through each successive cycle, the level that Bitcoin reached was massively higher than the prior cycle.â He added a pointed caveat for anyone still treating halvings as the metronome of BTC: âA lot of people believe the cycle is tied to [the] Bitcoin halving. The Bitcoin halving at this point is almost totally irrelevant [âŚ] when ETFs are accumulating inflows, the magnitude of those inflows is many, many multiples larger than any change in supply created by a Bitcoin halving event.â
Mitchnickâs framing puts Wall Street, not the protocol schedule, at the center of the next phase. BlackRockâs spot Bitcoin ETF, IBIT, âhas been the fastest-growing ETF post-launch in history,â he said, reaching milestones at roughly four times the pace of the previous record. More telling than raw AUM, in his view, is the changing composition of holders. In the first quarter after launch, âIBIT was over 80% direct retail investors. Every quarter thereafter that number has come down [âŚ] today itâs close to 50%,â reflecting the steady rise of wealth advisory and institutional channels.
That institutional cohort is still early, but broadening. âIf you think about the big categories of institutional investors, youâve got family offices, asset managers, sovereign wealth funds, university endowments, foundations, corporate treasurers, insurers, pension funds. You have some adopters in every one of those archetypes, but not the majority, not even close,â he said.
For those allocating, typical position sizes land in the â1% to 3% range.â The gating factor, again, is less about custody or accessâand more about how Bitcoin behaves inside a portfolio. âItâs all about correlation,â Mitchnick noted, recounting a conversation with a pension CIO who is âliterallyâ watching that metric. If Bitcoin persistently tracks âdigital goldâ rather than âlevered NASDAQ,â he argued, âitâs a slam dunk to put a couple percentage of portfolio allocation in it.â
The tension is that short-term market action still looks like crypto. Mitchnick called the October 10 washoutâroughly â$21 billion in liquidationsââa leverage event rather than a shift in fundamentals, and contrasted it with the steadiness of fund buyers: âWhat was the impact on ETF outflows? Tiny [âŚ] a couple hundred million.â That discrepancy, he said, is precisely why cycles should attenuate over time: a larger, slower-moving base of ETF and advisory capital can absorb derivatives-driven shocks without mechanically exiting.
He also pushed back on narratives that Bitcoinâs 2025 underperformance versus gold invalidates the âuncorrelated hedgeâ thesis. The digital asset, he argued, already banked its âdebasement tradeâ in late 2024, rallying from the âhigh $60s to over $100K,â and even notched a new all-time high around $126,000 before the October crash âderailed the momentum.â In other words, the year-to-date scoreboard reflects sequencing and leverage, not a structural repudiation of Bitcoinâs store-of-value pitch.
On supply dynamics, Mitchnick acknowledged that legacy cohorts have taken profits at psychological levels, but he dismissed the idea that Bitcoin is in an âIPO momentâ where early adopters permanently hand the float to institutions. Whatâs more plausible, he said, is simple risk management by ultra-early holders whose basis sits at â$100 or $500,â many of whom had $100,000 as a round-number trim target. âAt some point you do have to take some chips off the table,â he said, adding that long-term performance has favored patience over short-term, levered trading.
Mitchnick was careful not to oversell universal adoption among big pools of capital. Central banks, he suggested, remain a tail-risk buyer rather than a base case. The near-term path instead runs through the institutions already tiptoeing inâpensions, insurers, sovereign wealth fundsâwhose conviction will hinge on medium-term behavior and policy clarity.
The message for allocators facing their first full drawdown with ETFs live was direct: donât mistake derivatives noise for broken fundamentals, and be selective. âThereâs a reason Bitcoin is still roughly 65% of the market cap of the space,â he said. âOne has to be very wary going far down the table [âŚ] the vast majority of [tokens] are or will be totally worthless.â
For Bitcoin, the test is whether it keeps behaving like what institutions think theyâre buying. âPeople have to look beyond these short-term moves [âŚ] and more about, you know, medium and longer term how does it track,â Mitchnick said.
At press time, BTC traded at $105,497.
