Switzerland Gets a Spot Bitcoin ETF, While Quantum FUD Meets Its Math

The most interesting story of the week came out of Bern, of all places, and it arrived wearing the dry language of a fund classification notice. Alongside it came a quantum computing scare that calms down considerably once you look at the hardware involved, and ETF inflows that woke up a week before the Fed decides on rates.

Plenty to unpack, so let’s get to it.

TL;DR

• FINMA approved Switzerland’s first spot Bitcoin ETF for retail investors, granting a diversification exemption while noting Bitcoin’s market risk. The issuer expects SIX trading to begin in November.

• Google’s Willow chip cut a key quantum error rate roughly 40-fold, reviving the Bitcoin quantum debate.

• US spot Bitcoin ETFs took in $527 million on Monday, their biggest day in a month, as Bitcoin recovered from last week’s dip below $80,000 ahead of the October 28 Fed decision.

Switzerland Just Made Bitcoin a Retail Fund Asset 🇨🇭

On October 20, FINMA approved the first spot Bitcoin ETF open to Swiss retail investors, classified under Swiss law as an “other fund for alternative investments with specific risk.” Per the issuer, BIT Asset Management, trading on the SIX Swiss Exchange is expected to begin in November.

This one is personal for me. Switzerland has long been an early hub for crypto ETPs, the physically backed debt securities that have carried Bitcoin on European exchanges since the mid-2010s, and I co-founded one of the early European Bitcoin ETP issuers.

Back then, the idea that a Swiss regulator would let an actual investment fund hold Bitcoin directly for retail savers wasn’t on my roadmap, and I was in the room where those roadmaps got drawn.

An ETP of that type is a claim on collateral. A fund is a different legal animal, with diversification requirements designed to limit concentration risk, which is exactly what a single-asset Bitcoin fund runs into head first.

So the reasoning behind the approval arguably matters more than the approval itself. FINMA granted the exemption citing Bitcoin’s comparatively long trading history and high trading volume, while stating plainly that its market risk remains very high.

Quote both halves if you quote any of it. A conservative regulator didn’t exactly endorse Bitcoin here but concluded the market is deep and established enough that a diversification rule could be waived for informed retail investors with the risk disclosed.

In my experience, that’s the shape genuine normalization takes. It starts with approval with caveats, not applause. It also extends the pattern we’ve covered all autumn, from MiCA separating the field to the UK opening applications. Europe keeps building access routes while everyone watches Washington.

The Quantum Scare, Run Through a Calculator ⚛️

Google published a result in Science on October 15 that said its Willow chip reduced the error rate of so-called magic states roughly 40-fold, which is a genuine step in quantum error correction. Within days, my X feed was full of Satoshi’s coins at risk.

So let’s add the context the headlines skipped.

Willow has 105 physical qubits. Recent research estimates that attacking Bitcoin’s elliptic-curve signatures would take several hundred thousand physical qubits, and that’s under favorable hardware assumptions, as a theoretical resource estimate rather than a demonstrated attack.

Google’s own paper covers preparing and verifying quantum states, not extracting private keys. The researchers made progress and said so, and they never claimed anyone’s coins were in reach.

On the same day, nine crypto firms launched a Quantum Alliance to develop common post-quantum standards, estimating that 6.4 million BTC, roughly 30% of the eventual 21 million supply including an estimated 1.1 million coins attributed to Satoshi, sit in addresses whose public keys are already exposed.

Members disagree about the remedy, migration versus freezing, and Richard Carback, CTO of Postquant Labs, puts a threat timeline around 2028, a forecast other members of the same alliance dispute.

I’ll let the cryptographers argue the timeline, and I’ll grant that the incumbents aren’t standing still either. The BIS, for example, has been running its own quantum-safe experiments through Project Leap. My own view, unchanged for years, is that this is a real but solvable engineering problem, and the solving has visibly started on both sides.

I’d back an open-source network with one asset to protect and a global developer base to complete its migration ahead of thousands of institutions upgrading piecemeal. We wrote up the full picture in our quantum deep dive on the Samara blog. Worry budgets are finite, and this week’s result doesn’t deserve much of yours.

The Flows Turn Ahead of the Fed 💰

Bitcoin dipped below $80,000 last week on rate worries, recovered to around $81,500 by October 20, and pushed toward $84,800 on Tuesday as the ETFs staged their biggest inflow day in a month on Monday: $527 million, followed by more on Tuesday for roughly $550 million across two sessions.

Monday’s total was concentrated almost entirely in BlackRock’s IBIT, at roughly $665 million, while several other funds posted outflows, and October overall remains slightly negative, at about $65 million of net outflows through Tuesday per Farside. So this is not yet a broad turn. Whether it’s pre-Fed positioning is my interpretation, and the flow data can’t prove it either way.

The Fed decides October 28, with September’s dot plot still pointing to one more hike this year. I won’t guess what they do, and I won’t guess how the market reacts.

What four cycles have taught me is that the investors who did well through this stretch were the ones who stopped trying to trade the meeting and kept their eyes on the decade.

One for the Calendar 🗓️

MSCI announced new eligibility rules for non-operating companies on October 15, the policy that determines how index providers treat companies whose balance sheets are dominated by passive digital asset holdings. The constituent decisions land with the November 11 index review, effective after November 30. The treasury-company category will be watching closely, and so will we.

I’ll be speaking at the Bitcoin for Financial Services Summit in Denver, so come by and say hello if you’re attending.

Elsewhere in Bitcoin 📖

• Deutsche Bank plans to launch its digital asset custody service for institutional and corporate clients in 2026, subject to completion of the regulatory process.

• The comment period on the SEC’s proposed crypto custody framework runs until December 7. The final text will decide how advisers and funds hold Bitcoin.

• AnchorWatch Trust Company launched a Bitcoin custody service with optional insurance coverage of up to $370 million per client, more evidence that custodians now compete on the terms institutions care about.
