What happened

US spot Bitcoin ETFs extended their winning run to a seventh straight session through July 23, 2026, pulling cumulative net creations to roughly $981.2 million — a hair under the $1 billion mark and the category's cleanest stretch of demand since the June rout. On Wednesday, July 22, the funds took in about $69.1 million net, with BlackRock's [IBIT](/etf/IBIT) leading at $38.78 million.

But the number that actually says something sits one line down the flow table. Grayscale's Bitcoin Mini Trust ([BTC](/etf/BTC)) drew about $37.88 million — within a rounding error of the BlackRock behemoth — while Grayscale's original, higher-fee [GBTC](/etf/GBTC) shed roughly $38.3 million the same day. In other words, one issuer's own investors were rotating out the front door of the expensive product and back in through the cheap one, almost dollar-for-dollar.

Zoom out and BlackRock is still the engine: IBIT alone booked about $319.16 million over July 20-22 ($116.48M, then $163.90M, then $38.78M). Bitcoin held near $66,000 through the streak. The backdrop is the July 28-29 FOMC, where markets broadly expect the Fed to hold — the macro checkpoint every desk is trading around.

Why a 10-basis-point gap moves this much money

A 0.15% versus 0.25% versus 1.50% fee spread looks trivial until you remember what a spot Bitcoin ETF actually is: a pass-through wrapper holding the same asset. Once two funds hold identical coins under identical custody, the expense ratio is one of the only durable differences left, so fee is the variable rational money optimizes — and it compounds against NAV every single day the position is held. We walk through that math in cracking the code on expense ratios and liquidity.

The Grayscale-versus-Grayscale rotation is the purest version of this. GBTC still charges 1.50% — a legacy of its closed-end-fund past — while the Mini Trust (BTC) charges 0.15%, ten times cheaper for the same exposure. An investor sitting in GBTC is paying roughly 135 basis points a year for nothing incremental, so the migration into BTC isn't a bet on Bitcoin's direction at all; it's a fee-drag repair that shows up in the flow data as a paired out/in. That the Mini Trust nearly matched IBIT on a green day tells you low-cost issuers are competing at the flagship's level, not scrapping for scraps — the same fee-compression dynamic we flagged in the crypto ETF fee war and in the head-to-head IBIT vs FBTC comparison.

What it means for investors

Strip the streak down to mechanics and there are two different signals braided together — one about direction, one about structure — and they don't carry equal weight.

• The $981M streak is a sentiment read; treat it as fragile. Seven green sessions into a Fed week is a positioning story, not a structural one. Creation baskets follow risk appetite, and risk appetite is priced off the July 28-29 FOMC. A hawkish surprise can flip a $69M inflow day to a triple-digit outflow before the ETFs even reprice at the pre-market open — this same complex ran a multi-week outflow streak earlier in 2026. Don't confuse a week of green with a trend.
• The fee migration is the durable signal, and it's one-directional. Money that leaves a 1.50% product for a 0.15% one rarely comes back — nobody rotates *toward* higher fees. GBTC's slow bleed into BTC (and into IBIT) is a ratchet, not a cycle, and it will keep grinding regardless of what the Fed does Wednesday. For a holder, the actionable read is simpler than the flow headlines: if you're paying legacy fees on generic spot exposure, the flow table is showing you the exit other investors already took. Watch the premium/discount to NAV on the day you switch, size around it, and let the 135-basis-point gap do the rest.

None of this is investment advice. The takeaway is that a near-$1B inflow streak and a quiet dollar-for-dollar fund swap are telling you two different things — and on any horizon longer than the next FOMC headline, the boring fee story is the one with staying power.
