Bitcoin trader recovers wallet with help of Claude

I have a similar claude story (much less money though), with the IRS R&D tax credit. The auditing firm initially said we qualify for $0. But then I had claude analyze past R&D reports and our expenses and it found the problem. The auditor had miscategorized our company.

So claude drafted an email even pointing to the right Internal Revenue Code (IRS Law), and specify why we fall under a specific category. The auditor got back to me two days later admitting their mistake and said our company now qualifies for $8k in tax credits. And a few months ago, it identified items in our AWS that saved us $250 a month (paying for itself).

So now I joke that even if I have a claude max plan, I've still come out ahead financially.

This is no joke; for better or worse, I see a day when I'm paying a lot more for this and it will be a bargain.

By my estimation (guess) you won't actually need to spend that much because the models are already getting a point where they don't need to get a whole lot better to be extremely helpful across many domains.

And it looks like those very helpful capabilities will continue to transfer to smaller models as well, as architectures and training regimes continue to refine.

I can fairly easily imagine a world where the only people needing to spend a lot of money on models are those that are using them to solve truly novel problems. The rest of us will get plenty of use at reasonable costs for the typical day-to-day helpful stuff.

In 2023 GPT-4 was allegedly 1.8T parameters. In 2026 we have ~100x smaller models (10-20B) that handily outperform it, and can indeed run on a laptop.

by wolttam

5/14/2026 at 6:43:45 PM

It highly depends on the task. For math and coding, sure. But for knowledge tasks GPT-4 is wayy better than even SOTA ~100B models. For my knowledge test cases the lines get blurry at >400B

How does "outperform" translate to the propensity of an LLM to hallucinate?

by rectang

5/14/2026 at 6:13:57 PM

There seems to be a mass delusion about how capable SOTA models actually are. That's my only explanation for how poorly I find them performing in basic knowledge tasks compared to how others describe their prowess.

by operatingthetan

5/14/2026 at 6:22:55 PM

I understand you to be implying that I shouldn't trust my perception that there's a meaningful difference in how much different models hallucinate. I will take that under advisement, but I am still interested in the answer to my original question.

I am eagerly awaiting being able to run a strong local model. I'd hand Apple $5k right now for a Claude in a box. I know the cost might not be there now, just saying that is around my ideal price point.

$10k might even be worth it - but i'm assuming that the more expensive it is the beefier it is too, which also means more electricity.. and i already run ~6 computers/servers in my house. If a power surge happens i'm going to go live in the woods lol.

by unshavedyak

5/14/2026 at 6:05:21 PM

I would do the same but my issue is that the models are changing so fast, so I don't want to be left out of the next model cuz it only runs on an even newer GPU or something like that.

But maybe my limited understanding is thinking of this wrong.

by atonse

5/14/2026 at 7:07:57 PM

I wouldn't worry about hardware.

I've run the latest local models over the last year, including the recent Qwen 3.6 30B A3B, on a 9yo GTX 1080 and 32G RAM I have lying around[0]. If I can do that I don't think hardware will be a problem for you in the near term. The only updates I've needed were to Llama.cpp when a new class of model was released.

[0]: In my case, I want to see how local models perform on limited hardware, sacrificing context size and intelligence compared to SOTA models, so I have to really limit my expectations.

I think the same, and it's why i stopped caring about running llama/etc at home last year. That coupled with the models being dumb by comparison to SOTA really make me fine with waiting.

But in a year or two it's going to be difficult to resist at home, assuming the pace of improvement holds.

Yea, but i don't consider them good enough. I barely consider SOTA good enough.

by DANmode

5/14/2026 at 6:00:19 PM

In my anecdotal experience there is a huge gap between GPT-5-mini which hallucinates relentlessly and Claude Opus or the latest GPTs which are fairly reliable. I'm hoping that gap can be closed with improved approaches for small models and that good reliability is achievable for LLMs without requiring absolutely mammoth computing resources.

For what it's worth, I also used GPT-5.2 (via duck.ai) this year for questions about taxes and it was helpful — which makes sense because there's an abundance of material about taxes out there to be synthesized, so a text predictor trained in that domain should do well.

[sci-fi “AGI” scenario] What if those with elite model access philosophize in a way us mere mortals can’t understand, so the elites have to prechew the ideas for us to bring them to our level, and they control the narrative?

In reality now, curious about social implications generally. Does this go beyond problem solving? Maybe the intelligence per token you get via your free library card/membership is insufficient to compete with peers in dating/employment/etc. markets, thus puts you at disadvantage.

by Barbing

by DANmode

5/14/2026 at 3:44:23 PM

To be fair regarding taxes it should be that you get all exemptions by default and the other side telling/justifying you why you don't qualify, instead of you not getting the things you should because you're not sure how to interpret the law or don't know this or that rule exists. Taxes shouldn't be that difficult, and the US version of it seems to be behind even the one I have here in europe (where my taxes are done "for me" for anything non business owner related). If the government is calculating your taxes anyway, they should just give the number to you instead of asking you a number and you better have the same as us or you're guilty of something.

Feels like a system that is deliberatly made to be more punishing for those who can't afford the help or the education to figure things out.

by nolok

5/14/2026 at 4:08:00 PM

I would agree with you on most situations (like 1040 personal income taxes especially).

But in this particular tax credit, there's no way for the gov to know automatically what percentage of payroll was spent in qualified R&D expenses, since it's day to day business operations. Which is why we are _forced_ to hire an outside firm and pay them thousands of dollars (when Claude did an even better job), just to analyze how much of our time qualified as R&D expenses.

The problem I have is that I am forced to have to find a firm to do this, and most firms won't even work with companies as small as ours. So then we're stuck and losing out on years of R&D tax credits at the moment, when I really don't need them anymore, to be honest.

Can you explain the steps you followed? Did you just feed it the whole return?

by gonzalohm

5/14/2026 at 5:36:35 PM

Kind of. I first of all did the entire return with it. So we went step by step and yes I fed the forms one at a time. So I filled in 1040 as best I could. Then just asked it what to do next at each step. It helps I've done it before so most of the steps it returned were ones I've done before. However, it did mention several things that I had not heard of, and also some new taxes that I had to file due to some exceptional events last year. So all in all, a solid use case. This year I have an accountant, but it saved my butt this last year, and I will absolutely run through my accountants decisions with it. It has an encyclopedic knowledge and an immense capability to understand without getting tired.

by fragmede

5/14/2026 at 7:12:03 PM

People's tax returns are essentially public (yes I know they're not allowed to disclose them). Didn't send the forms in with social security numbers.

This absurd concern for privacy is silly in my opinion. The moment something is submitted to the government it ought to be considered public. Even your social security number is essentially public for anyone who cares to find it.

I would not submit my bank account information to these services, or my passwords, obviously.

Honestly, tax returns should be public again. Would make everyone better behaved IMO. It was this way for most of American income tax history believe it or not.

To be clear, my information has already been part of several breaches anyway. What protects you ultimately is the law not information security. Of course this point is often lost on engineering / computer scientist types who don't understand how law works.

I use AI to help me do my accounting (how to categorize and account for things). It pays for itself because I need to spend money for far fewer hours from an accounting firm each month to make sure that captialized expenses, depreciation, tax credits (we have Historical Tax Credits from restoring an 1880s building) etc, is put in the books properly. The AI gets it right a high enough percentage of the time that I only the to have a real accountant look at things once a quarter to make sure it's all OK. I used to have a dozen questions every month.

Claude Code is really good at stuff like this. The other day I tried to recover some images from an SD card that had gone bad. I used GetDataBack to recover files, but they appeared to be malformed and didn't open in image viewers.

I tasked Claude to analyze the files and figure out what's going on, and eventually we figured out that each file had a custom metadata header + thumbnail + actual image concatenated. I had it write a python script and was able to recover all the images with their metadata. It's nothing a human couldn't have figured out, but it was definitely WAY faster than doing it myself.

I've also used Claude in the past to figure out how to break into routers with locked down firmware. It's great at suggesting and trying different approaches.

I have a friend that just picked up a new consulting job resurrecting an ancient Windows desktop application. No source control, no tests. And it's spread out over a dozen different folders with names like "_old", "_new" and "dates". Claude's doing a tremendous job in getting him to grips with what is actually happening in the application, what's relevant, what's not, what's different. I think it's literally saving him days and days at work.

That doesn't sound very impressive. Not being tracked with a version control system is fixed instantly with a git init, git add ., git commit .no AI required.

Covering the app with tests is also something that requires no AI. At most, coding agents can generate characterization tests in broad sweeps, but we are talking about a delta between hand rolling and vibe-coding of a couple of days.

Where LLM shines is helping developers build up an understanding of what is in place. Running /explain on a codebase can quickly provide you with a high level summary of what's in place.

by locknitpicker

The relevancy here is that he's denied the git history, versioning, branches, implicit documentation that even bad source control practices would have given him.

by michaelbuckbee

5/14/2026 at 4:35:48 PM

That's what the comment is saying. In normal repositories, version control acts as a record of the momentum of the direction the product was taking. If it's just "_old" and "_new," the developer has to read and understand both, which I think is going to be far more time consuming than your estimation.

I'm sure data recovery companies are pretty pissed that slightly esoteric data recovery abilities are becoming more accessible for average software devs. They were charging an arm and a leg to remote in and run scripts.

by arm32

5/14/2026 at 3:30:31 PM

They still have two important moats: (1) expensive hardware tools (even stuff like SATA write blockers are kind of expensive for what they are), spare hard drive collections to swap failed PCBs, etc and (2) the "nobody got fired for hiring us" edge similar to how everyone calls in Crowdstrike/Mandiant after an incident. If a suit-level manager finds out customer data was lost, they are going to want to call in an expert so they can immediately tell the customer they did, not have the same internal team try to figure it out.

by morpheuskafka

5/14/2026 at 3:59:34 PM

As an aside to #1: The cool thing is in modern times the hardware tools have come down stupidly cheap in price. Even SD card recovery is (vaguely) in the right skilled hands in a pseudo-professional home lab these days.

A lot of "Claude Code is best at X" claims are probably user-selection bias.

The people saying it are often exclusively Claude Code users, not people who are actively benchmarking Claude Code against Gemini CLI, OpenAI Codex, GitHub Copilot, and other agent harnesses on the same tasks.

The claim may still be true for certain scenarios, but the evidence is usually anecdotal, not comparative.

by brunoborges

5/14/2026 at 4:39:05 PM

When I hear "claude code one-shotted X" and X is a novel problem, I mentally substituted "the agentic harness that I tried one-shotted X," since that's what they're saying.

Getting any smart model to take a look at the task is the sort of lift that the speaker is usually pointing to.

by gcr

5/14/2026 at 8:25:17 PM

The harness is pretty much irrelevant for general tasks.

You can write a 100 line harness that only has one tool - try either "bash" or the more fun "you're running within nodejs, here's eval", you'd be surprised in how close to CC/Codex performance you're going to get.

by nananana9

Explaining your life to an llm, then having it generate permutations of passwords to try does sound like it would work a decent percentage of the time.

A large percentage of passwords aren't a random string of characters but a memorable word + memorable number. There's existing projects that basically do the same, and 3.5 trillion doesn't really make it clear if one of those wouldn't have worked as well, but I can see it having an above random chance to guess a password.

by ApolloFortyNine

5/14/2026 at 6:35:29 PM

>Explaining your life to an llm, then having it generate permutations of passwords to try does sound like it would work a decent percentage of the time.

I cannot relate to this at all. This information doesn't really seem that helpful. What might the strategy look like? Including spouses names or other proper nouns associated with you. But it's going to be a massive brute force effort still, and the likelyhood of a targeted crack that performs significantly better than more naive brute force passwords seems so unlikely.

Are your passwords like "SPOUSE_NAME:HOMETOWN_NAME"? Even if so there are probably more people with dictionary words that can be brute forced faster. IT would have to be the case that more people use patterns like that compared to something a regular dictionary attack could crack.

by nonethewiser

5/14/2026 at 9:16:26 PM

Way back in the day when Bitcoin first came about, I once idly contemplated spending some time and money on it just because it was a very cool technology. At the time it was a bit of a hassle because you had to mine your own.

Then I was especially tempted years later after running into the MtGox booth at CES, and seeing how convenient it had become. I remember asking a guy at the booth if Satoshi was really still anonymous or if any insiders knew about him, and he said "no" but was bit surprised I knew about Satoshi. I guess Bitcoin was still quite niche then even amongst a technical crowd.

I considered buying a few bucks worth of bitcoin then for lulz, but I thought that money was better spent on beer lol.

I've never really regretted spending that money on beer rather than bitcoin, because I knew that even if I did, it would 100% have been on MtGox and I would have lost it in the hack anyway, which would have been even more bitterly frustrating.

A few of pints of beer >> years of regret.

Yup. I was really close to buying $1000 (at $1) worth of BTC ages ago. I don't dwell because the stress of managing that through time would have eaten me away lol.

With that said, i do regret not at least mining/etc. Back then i could have mined in many ways, and getting into it as a hobby probably would have meant holding larger amounts of BTC in the long run.

I remember thinking about buying $100 (at $10). And then realizing I didn't actually know how to do it and didn't feel like looking it up or going through whatever steps to do that kind of transaction online, or worrying about getting scammed....

A friend lost £2000 worth of BTC in MtGox which is probably worth a fortune at today's prices. The last time I spoke with him he said there was some sort of lawsuit for victim compensation. How did you recover your funds?

by echelon_musk

They emailed us during the course of the lawsuit, I followed the instructions and they sent me maybe half my BTC in the end.

Many crypto wallets use a key derivation function (KDF) to add an amount of computation (and memory usage) per password tried - to mitigate brute force of weak passwords.

The increase in compute (decrease in brute-force cost) combined with price increases in many crypto tokens means brute-forcing old wallets can become worth it years after passwords were forgotten.

And of course even smaller, local AI models can now easily write optimized scripts to brute-force any given KDF function.

by ndr

5/14/2026 at 5:12:16 PM

The compute power needed use to be of the order of 5s per password try. So it effectively mitigate brute force back them, you need a absurd compute power to crack them.

Moore law did its thing, now you can do it with a lot less computer power.

by _ache_

5/14/2026 at 6:02:53 PM

Still, they didn’t give up because that wallet contained 5 BTC; this may not sound much, but it has a value of almost $400,000.

I'm no expert but using an old wallet with a changed password, and it working, seems like a major security design flaw.

In the physical world, I can't imagine too many people being happy that old keys to your house still work even after you've changed the locks.

Can someone more informed, help me understand how this worked and why it's ok.

I'm genuinely wanting to become more informed & better understand.

by tiffanyh

5/14/2026 at 4:26:18 PM

A wallet is just private keys of some specific public keys on the blockchain that have unspent output (UTXO). None of what’s described in this article involves the blockchain, only the storage and protection of the private keys on a local computer.

You can imagine that in your example, you didn’t change the locks on a house, but rather you put the house keys in a secure lock box and you changed the locks on this box.

Changing the locks on a house in this case means transferring from an old wallet to a new wallet and then abandoning the old wallet. That’s exactly what the OP is trying to do. It’s just that you need the original key to do it.

by kccqzy

5/14/2026 at 4:14:02 PM

They didn't lose the key, they just didn't know which one is the correct one, where the lock is, and how the unlocking is done.

by bornfreddy

5/14/2026 at 4:46:33 PM

The wallet is akin to a lockbox holding your keys to the house. Breaking into the lockbox and changing it's lock does not affect the keys kept inside.

I spent a couple of days mining many years ago and got 2 bitcoins. At the time, they weren't worth the electricity they cost to mine and over time I lost the wallet and all information related to it.

I'd love to mine a bitcoin a day on my PC now...

you can!... but they wouldn't be worth the electricity now either. the cost of mining (amortization of hardware costs plus electricty) is the value of bitcoin. if bitcoins are a bargain to mine, more people will mine them thereby reducing rewards.

should you have mined more back then if you had magical perfect knowledge of the future? no: they weren't worth the electricity.

instead you should have bought more of them back then.

by fsckboy

There’s an interesting ethical question here.

The other day, I asked Claude to track down the leaked Claude Code source so I could study it. It refused, saying “given who made me, I’ll pass.” It gave me some pointers on how to find it myself, which worked.

There isn’t that much of a difference between “help me crack this bitcoin wallet” and “help me crack this executable.”

I don’t exactly have a solid point, just some general observations. First, I think we’ll see AI more and more simply refuse to do any kind of forensics, as forensics becomes more powerful. Second, that implies local models will become more valuable, since they’re the only ones willing to do that kind of work.

I once got myself banned from Claude by researching barbiturates, since they’re connected with suicide. So my third observation is that we’ll see an uptick in people getting punished for trying to do things with AI that people don’t usually do. (Luckily the unban form worked.)

Someone downthread asked “how’d he convince Claude the coins weren’t stolen?” Which is an interesting question, because presumably some people trying to crack a wallet have stolen it. So I guess the fourth observation is that the exact framing you approach an AI with will become more important. There was the classic “do this or I’ll cut off my arm,” which worked a year ago. But in the future it will be more like “hopefully the AI believes my story, or else I’ll get into trouble.”

It’s good there are multiple AI vendors, or else it’d get real dystopian real fast when the de facto AI’s policy becomes something you have no way of working around.

Kind of cool to hear... I had a couple computers running miners at home towards the end of my second marriage (which ended in 2010-2011), and after I had a few coins when realizing I couldn't actually spend them (IIRC $0.25 at the time), I just deleted the wallets. I had no foresight or faith that they'd be worth around $100k each in 15 years. I'm curious how many did the same, how many coins out there were just deleted altogether.

by tracker1

5/14/2026 at 5:54:18 PM

by chasd00

5/14/2026 at 9:14:14 PM

I might have been your co-worker.

I went from giving them away to anyone in the office who asked (very very few), to selling them for under market when they were in the $10-50 range. Only three people took me up on the offer then, and they bought moderately life changing amounts I've later been thanked for. Such as a down payment for someone's first home after he got married. Luckily they held onto enough of their coins to make a meaningful difference in their lives like I preached about at the time.

The number of folks who ping me at various BTCH ATH hitting the news is expressing regret and laughing about it is... a lot!

It was strange being the "Weirdo Bitcoin guy" for a time. Then you started hearing about it in the mainstream news/etc. and it got even stranger to me.

I did quite well for myself, but of course wish I could go back in time and actually go balls to the wall on my early mining operation. I thought I was being irresponsible enough as it were - maxing out my rental townhouse's electric service with a rack of GPU miners in my basement, and some sketchy DIY electrical work to make it all happen.

Unfortunate to me cryptocurrency devolved into such a horrible place with the shitcoins, etc. I dropped out from the scene fairly early since I was a True Believer and became quite disenchanted with the whole thing. All I was there for was "digital p2p cash" - I never once foresaw it as a major store of value.

by phil21

5/14/2026 at 7:13:18 PM

One can't help but observe the contrast between counterparty behavior here vs. the crypto boom. A counterparty service had a secret worth 400K in-hand and just passed it back to the user. Meanwhile crypto worries about MEV, the Dark Forest, etc.

This cycle is hostile in lots of ways, but the trustworthiness and absence of hostility in this dimension is quite nice.

The story is confusing some people.

Claude found a file on the computer that the wallet owner had not found. Claude didn't crack a password or do anything magic, it just searched for a file that the wallet owner had not thought to search for before.

So, where the wallet owner had previously only tried to access /Users/example/wallet.dat, Claude thought, "why don't I check if there is another wallet.dat file elsewhere on the system?" which it did.

The outcome is the same, it is great that Claude tried something that the wallet owner hadn't tried, but this is more an example of how dumb humans can be rather than how smart Claude is.

The trillions of passwords are a red herring and unrelated to the solve.

On a purely technical level - cool. But I still cannot get over the impression that even in this case LLMs show us how they are mainly useful to grifters. I mean, 5 Bitcoins worth 400K USD. Why? What intrinsic value does Bitcoin deliver? It's like trading for monopoly money.

by zahlman

"the user dumped their entire college computer files in Claude in a last-gasp effort."

Claude has limits that would make this simple statement be much more complicated-

Via Claude "So the chat upload file size limit is actually 500MB per file (not 30MB as many third-party sources claim - those appear to be outdated). The 20-file-per-chat cap and the 30MB-per-file limit in Projects remain consistent across plans. The real constraint at any subscription level remains the context window - how many tokens Claude can hold in memory at once during a conversation. "
