What Happened in Bitcoin Today? ETF Flows Flip Again as Structural Buying Builds Underneath

BlackRock's buying reversal from yesterday already reversed again, but corporate treasuries and shrinking exchange supply suggest the structural case is stronger than the daily flow whiplash suggests.

Bitcoin Climbs Past $63,900 as ETF Outflows Return 

Bitcoin is climbing again, up 1.19% on the day and continuing a recovery from $62,550 support. That's the least interesting part of today's picture. The ETF story that looked like a turning point yesterday already turned again. 

ETF Flows Whipsaw Again, One Day After BlackRock's Reversal

BlackRock's return to buying lasted about as long as it took to report it. US spot Bitcoin ETFs lost a net $85 million on Wednesday, ending the three-day, roughly $509 million inflow run that had included BlackRock's own reversal. The outflow was broad and cleanly sourced: IBIT shed about $59 million, Grayscale's GBTC lost nearly $64 million, and Fidelity's FBTC gave up about $15 million, only Grayscale's mini BTC product stayed positive, at roughly $53 million, netting to the $85M figure.

Ether funds moved the opposite way, extending an inflow streak led by Fidelity's FETH. Ether has outperformed Bitcoin over the past two weeks on its own narrative (the Lean Ethereum roadmap) and returning ETF demand.

Underneath the ETF Noise, Structural Buying Keeps Building

While daily ETF flows swing between headlines, two slower-moving signals point the same direction, both cleanly corroborated across multiple outlets. 

Public companies purchased roughly 110,000 BTC in the second quarter, pushing total corporate treasury holdings above 1.26 million BTC. More than 6% of total supply now sits on balance sheets rather than circulating. Separately, Bitcoin held on exchanges has fallen to its lowest level since 2017, per Santiment with fewer coins sitting in immediately sellable positions.

• A third data point is circulating this week too: reports of a sharp rebound in Bitcoin futures demand, framed as institutional positioning turning constructive after a weak start to the month.

None of this guarantees the ETF outflows reverse again soon, but it's a different kind of evidence than a single day's fund flow: slower to build, and slower to unwind.

Fed Williams Flags AI-Driven Inflation as a New Risk to Watch

New York Fed President John Williams said this week that AI-driven demand is now his primary inflation concern, elevated spending on data centers, semiconductors, and electricity pushing prices up rather than the deflationary effect crypto markets have generally assumed technology adoption brings. 

Williams projects a return to the Fed's 2% target now pushed to 2027, consistent with the New York Fed's own recent remarks describing a glide path landing on target by 2027–2028.

• This matters for the structural-buying case above: sustained institutional accumulation is easier to argue when rate policy is expected to ease. If AI-driven inflation keeps the Fed hawkish for longer, that's a headwind the corporate-treasury and exchange-supply signals will eventually have to work against, not just complement.

If the Fed keeps rates higher for longer because of AI-driven inflation, that makes it harder for big investors to keep buying Bitcoin. Even though companies stockpiling it and less BTC sitting on exchanges are good signs right now.

The Lesson

A single day's ETF flow reversing is not the same signal as a structural buying trend reversing. Corporate treasury purchases and shrinking exchange supply move on a monthly or quarterly clock; ETF flows move daily and can flip on sentiment alone. Weight them accordingly.

Patterns like this tend to repeat across cycles. The Coinjuice ebook walks through reading chart structure the same way. One repeatable shape at a time, without needing leverage to have conviction.

Coinjuice Lens: Market Structure

Yesterday's piece asked whether Bitcoin's bottom was in on the strength of BlackRock's reversal. Today's outflow is a reminder that any single fund's daily move, in either direction, is a data point, not a verdict. The slower-moving structural signals are where the more durable case actually lives.
