The thread turned out to be about Super Intelligence (SI) maths as much as quantum computers. The honest version is narrower: ECDSA and Schnorr are one door with two kinds of key, most coins are protected by a hash rather than a curve, and what differs between the two threats is warning time, not which door is at risk. bitcoin quantum computing cryptography ecdsa schnorr taproot bip-360 post-quantum self custody https://ledger.m8k.io/will-the-us-government-buy-stocks-checking-karsans-big-print-call.html https://ledger.m8k.io/will-the-us-government-buy-stocks-checking-karsans-big-print-call.html Thu, 08 Oct 2026 12:00:00 +0000 A 69-minute interview says the US will print money and buy stocks through a sovereign wealth fund, probably after the midterms and after a 25 to 35 percent crash.

I went to the study. Thirty-six chatbots, twenty-eight distinct questions, and a spread from 91.3% to 18.3% that tells you more about who trained the chatbot than about money.

A viral post set that beside JPMorgan's "operational floor" of 6.8 billion and implied the line had been crossed.

I went and found the actual committees — six unnamed people at MSCI who can decide whether Bitcoin counts as an operating asset, a board at FTSE Russell that is contractually forbidden from naming its own members, and the one index manager anyone actually knows by name, only because the SEC caught him trading on what he knew.

That's the Kremlin's own case for why the war continues — existential, civilizational, not up for negotiation. I wanted to know what that case looks like from the inside, and once I went looking, I found something more concrete than rhetoric sitting right next to it: $300 billion frozen, a payments system Russia no longer trusts, and a very specific, very measurable pivot toward crypto rails that started well before this month's headlines. russia bitcoin sanctions crypto regulation de-dollarization oil trade gold medvedev ukraine war https://ledger.m8k.io/the-jar-ships-what-it-promised.html https://ledger.m8k.io/the-jar-ships-what-it-promised.html Wed, 30 Sep 2026 12:00:00 +0000 Two things I flagged as "he says so, but I can't see it yet" in my last two Lightning in a Jar posts — a recovery scheme for silent payments, and Nostr Wallet Connect — showed up in the public repository overnight.

I went looking for what it actually reaches, using two Kankakee residents as the test case: one who owns a Bitcoin ETF inside an ordinary brokerage account, and one who wants to buy coffee with sats over the Lightning Network. The tax lands hard on one of them, barely touches the other, and can't see the actual coffee purchase at all — and the reason why says a lot about how a state can tax a ledger it doesn't control. bitcoin lightning self-custody etf taxes tax policy crypto regulation illinois notes https://ledger.m8k.io/the-coins-exchanges-wont-let-back-in.html https://ledger.m8k.io/the-coins-exchanges-wont-let-back-in.html Tue, 29 Sep 2026 12:00:00 +0000 CoinJoin — a real, measurable Bitcoin privacy technique — mixes coins in a way that risk-scoring vendors flag and some exchanges won't cleanly accept back.

A New York Times investigation says Silicon Valley is already bracing for the underclass that leaves behind. And I keep getting told, in real time, that Bitcoin is the one thing standing between any person, company, or AI agent and what comes next.

Bitcoin's pitch to the same reserve managers isn't replacing gold, it's being gold with an API: instantly portable, verifiable without an assay, settleable in ten minutes instead of a bonded shipment.
