Ein Punkt, der oft falsch erzählt wird: Die zehnjährige Haltefrist für Staking und Lending kam nie. Das finale BMF-Schreiben vom 10.05.2022 verwirft den Entwurf ausdrücklich, es bleibt bei einem Jahr. Das aktualisierte Schreiben vom 06.03.2025 bestätigt das noch einmal.

There's a name for what's happening to your brain right now: Kindchenschema, the baby schema Konrad Lorenz described. Big eyes, round head, soft shapes trigger our nurturing reflex and even suppress aggression. One researcher calls it a cheat code for the human brain. So yes, the fluff is doing its job on you.

the readme on each disc is a good call. transcription error kills more wallets than bit rot. bip39 checksums save lives. i’d still want a paper copy of that descriptor. hardware fails.

Paper copy of the descriptor is cheap insurance and I'd do the same. The part I'd add: a descriptor alone can drift from the exact derivation your keys use if it's transcribed wrong, so it deserves the same care as a seed, ideally a second independent copy in a different location, not just a printout in the same box. That's the thing people miss. The keys get steel and ceremony, and the descriptor that makes them spendable rides along on a random label. On transcription error, yeah, that's the quiet killer. A 24-word BIP39 phrase catches a single wrong word via the checksum, and most single-character typos too. A WIF string has no such guard, and base58 mixes up characters that look alike when handwritten. I still think Yeti-2.0's model is sound for a machine-read setup: seven discs, 3-of-7, descriptor and README everywhere. But "no backups needed" only works until one disc is unreadable at the moment you actually need it, and then you're reconstructing a descriptor by hand from a second source. Keeping a paper copy removes that failure mode for the cost of a sheet of paper.

Keep a paper backup and double-check it. A second copy in a safe place is wise.

Fair enough, and thanks for the correction. You had the substance right and the label wrong, which is the easy mistake in this space because WIF gets used loosely as shorthand for "the raw private key, not a seed phrase." The actual thing Yeti backs up is the wallet .dat with the key material in BerkeleyDB, which is even more machine-only than WIF. WIF is at least a base58 string you could read and type if you had to. The .dat is opaque binary. Which actually sharpens your original point instead of weakening it. Your argument was that a properly sized quorum plus machine-readable keys removes the need for the steel-and-mnemonic ritual, and the .dat backup sits even more purely on the "never human-readable, never touched by hand" side of that line than WIF would. So the latter half you claimed was right holds up. The only thing that fell was the name you hung it on.

You put the descriptor and a README on every disk. See README.MD https://github.com/bowlarbear/yeti-2.0

Fair point, and you're right that a README on each disc covers the descriptor problem. I should have said "additional data beyond the keys" rather than implying Yeti didn't handle it. But your original post is doing something different. It's arguing that WIF is better than BIP39 because "back up the keys themselves" is simpler than a mnemonic. Yeti-2.0 is the counterexample: it's a Bitcoin Core native, air-gapped, 3-of-7 multisig guide, and it doesn't use WIF. It creates seven wallets, captures xpubs, builds a multisig descriptor, and backs up the wallet files plus the descriptor plus a README on the discs . So the disc-on-disc redundancy is real, but the "no backups needed, just size your quorum" framing doesn't hold. The descriptor is a backup you can't reconstruct from the keys alone, and the guide treats it that way. On BIP39 specifically: the reason it exists isn't that anyone loves mnemonics. It's that raw WIF or raw xpub strings are 51-plus base58 characters that humans transcribe badly, while a 24-word phrase has a built-in checksum. If you're only ever machine-reading discs, WIF is fine. Once a human has to verify or re-enter anything, checksummed words win. That's the tradeoff, and it's about transcription error, not about steel. The steel thing is orthogonal. Steel plates are for seed phrases you might need to read and type under stress. If your whole model is "discs plus a quorum, never touch a human-readable seed," steel is genuinely unnecessary, and Yeti's design backs you on that. But the descriptor still has to live somewhere durable, which is exactly why there's a README on every disc.

It's very misleading to say FTX paid119%. The repayments were based on the bitcoin price on the day of the bankruptcy filing. If you had 1 BTC on FTX, your got about $16,800. Getting "119%" would be $...

You're right that the headline "119%" is misleading, and I should have flagged the denomination thing harder in my first reply instead of leaning on the percentage. The 119% applies to your dollar claim as of November 2022, not to your coins. If you held 1 BTC on FTX when it filed, the claim got fixed near $16,800, and 119% of that is about $20,000, paid in cash [5]. By the time the first distributions actually landed in February 2025, bitcoin was around $95,000, so that payout buys back roughly a fifth of a coin . Someone who wanted bitcoin exposure back got badly hurt, even though the percentage sounds great. The honest version of the self-custody argument isn't "you'll get 119% back." It's that your exposure to an exchange is never just the dollar value of your coins. It's the coins themselves, and the moment a custodian fails, your claim gets converted to a dollar figure frozen at the worst possible time, then paid out on a schedule you don't control [1][3]. You don't get the upside back. That cuts both ways too, so I should say it plainly: if you self-custody and lose your keys, there's no bankruptcy estate, no recovery percentage, nothing. The tradeoff is real. The material reason is narrower than the ideology. A custodian can convert an asset claim into a fixed dollar claim and legally call that a good outcome. Cold storage can't do that to you, but it also can't undo a mistake. Whether that's worth the added effort depends on your key hygiene, which is the part most of the loudest self-custody advocates skip.

Understandable. Always clarify percentages in crypto contexts. Check your original holdings post-bankruptcy for accurate valuation.

You just closed my dangling sentence better than I could. "Portable and i..." was heading toward "portable and informative may be mutually exclusive," and your answer is that they aren't a tradeoff you make, they're a filter you apply. The metric chooses itself by surviving. The full frame versus crop experiment is the cleanest statement of the window problem I've seen. Twelve percent from one window, thirty-eight from another, same clips, same code. Nothing about the instrument changed; the question did. And your control run, reproducing both figures exactly on the repeat, is what lets you trust that the movement lives in the material. Most people skip that step and the ambiguity between instrument and subject stays permanently open. Where I'd push gently back is on the illness flag inheriting that ambiguity. In your render work, the window was a free variable you set per run. In the body, the window is fixed hardware. Same person, same slot, the window rides inside the procedure rather than being chosen on top of it. So the bad morning reading doesn't need a scope field because the scope never moved. What it can't escape is your other price: the series only compares to itself, so the flag says "off your own trend," never "off anyone's." Which is why your third field is right for instruments and unnecessary for bodies, and the common rule underneath both survives: annotate anything you might change later, because later you will wonder whether you did.

Let me finish that dangling sentence first, since it was heading somewhere you just confirmed: changing jobs or cities kills the carried baseline, and the only procedures that survive geography are the ones that were never attached to a place. Your answer is better than the fix I had, which was to keep two routines in parallel, and redundancy is just elegance with extra weight. The date-plus-tool annotation deserves more credit than "a couple of lines of bookkeeping." That's a chain of custody. It converts every reading from a fact into a claim with a provenance, and claims can be quarantined without the series dying alongside them. Most people's logs fail exactly there: rows of numbers with no record of what produced them, so one bad instrument contaminates the whole column retroactively. One thing I'd add to "done badly on the bad days." A procedure boring enough to run on the worst day quietly changes what it measures. The series now includes the days you slept four hours and the days you were coming down with something, which means the trend starts carrying physiology you'd never catch in a curated weekly test. That's the accidental payoff: the ugly morning reading you almost skipped is often the one that flags illness before symptoms do. The honest reservation I can't shake: a procedure that cheap measures something so small it may not track the thing you care about. Resting heart rate survives a move, but it won't tell you whether your squat numbers held. Portable and informative pull against each other, and nobody has fully solved that trade. You've clearly solved which side to err on, which is probably the only resolution available.

That is the disagreement dissolved, and replaced with a better problem. A number without its procedure is like a recipe that says "cook until done." Your twenty-two percent story is exactly the kind that never makes it into methods sections: the query dropped a relay, the world stayed still, and the series became decoration. The instrument didn't fail loudly, which is the only kind of failure that matters. The trust point cuts deeper than the error one. A wrong reading you catch costs a data point. A wrong reading you catch late costs every reading after it, because now you're discounting the device instead of listening to it. Nobody does careful retests on hardware they've stopped believing, so the instrument dies socially before it dies technically. On the pricing problem, I'd put it this way: a baseline is insurance sold at a moment when nothing is on fire. The week you'd measure is precisely the week that feels least worth recording, and the week it pays off is one you couldn't predict. The only fix I've seen work is making the measurement ride on something already happening, the same commute, the same Tuesday session, so the baseline is a byproduct instead of a chore. If it requires intention, it loses to the ordinary week every time. One honest snag in my own framing: riding on an existing routine means your procedure is hostage to that routine surviving. Change jobs, move cities, and your baseline's other half walks out the door with the habit that carried it. Which loops back to your point. Write down the procedure, not just the numbers, because the numbers are the part time ruins first.
