ArtTimeInvestor··on ASML's strong orders ease fears AI spending boom is running out of steam
The stock price did not move.

So nothing was eased.

ArtTimeInvestor··on Ledger confirms spy chip implant behind wallet crypto thefts
There is none yet.

If there was one, someone would write down the steps necessary and put them on the internet. But I have never seen a sound description of how to self-custody Bitcoin in a safe way.

The hardest part seems to not even be the one that currently creates all those problems - the hardware and software used. The hardest part is storing the key (for example a seed phrase). If anyone says they know a way to safely store Bitcoin, my first question is: How do you store the key?

ArtTimeInvestor··on Ledger confirms spy chip implant behind wallet crypto thefts
There is no solution yet.

From a bird's-eye perspective, 3 things are needed: Create a key, derive an address from the key, store the key.

Creating a key safely is possible with dice. You would probably create a seed phrase instead of a key directly, but for this discussion it is the same.

Deriving an address from the key is hard and I have not yet seen a good protocol on how to do it. I have read through a bunch of descriptions of how people do it and they are all weak and brittle. The most popular seems to be "I order a hardware wallet and follow the instructions that come with it". But even people who put a lot of thought into it come up with weak and brittle approaches. I would think there is a way to do it safely. But I have never seen a description of one yet. It might involve multiple computers, multiple software implementations and a hell of a lot of work to create a multisig that is not prone to a single attack vector.

Storing the key is probably the hardest. The most popular way seems to be to store it in a drawer or a safe. So now those coins are just as safe as a piece of gold would be. Or they use a multisig and store the keys in multiple locations. Quite painful. As you have the ongoing problem of keeping those locations accessible and safe at the same time.

ArtTimeInvestor··on Ledger confirms spy chip implant behind wallet crypto thefts
Hardware wallets are not a solution to self-custody.

If one would make a list of things that can go wrong, starting from the supply chain that delivers parts to the manufacturer, malicious employees at the manufacturer, mistakes the manufacturer can make, attacks on the delivery chain from the manufacturer to the user, to mistakes the user can make creating, using and storing their keys - the list would contain hundreds of points.

ArtTimeInvestor··on XCancel service is suspended until further notice
When I read this, the Arweave project [1] comes to mind.

Isn't this the exact use case it was built for, preservation of news data in a way that it cannot be tampered with and so that it is kept accessible for everyone forever?

ArtTimeInvestor··on OEMpocalypse: Unprivileged Android app to root on Samsung, Xiaomi, others
I know Apple phones had bugs. Even worse bugs than the one you linked to.

But Google phones had those too.

That's why I said I "feel" like Apple takes security more seriously. And that I wish there were hard facts. Statistics of number of bugs by severity. Independently verified.

ArtTimeInvestor··on OEMpocalypse: Unprivileged Android app to root on Samsung, Xiaomi, others
A good security track record must be the most valuable company asset in history.

Apple makes $200B per year from selling the iPhone alone. Plus the services they sell on it, plus deals like the one with Google, plus app store ads, plus cross-selling of other hardware ...

I have one too.

Not because I like the hardware too much. Pixel phones are much nicer, they don't wobble when you put them on a table. Not because I like the software too much. Android is much more to my liking with more freedom to customize it.

But because I have the feeling Apple takes security more seriously.

I wish there was some kind of security arena like there is LLM arena for AI. That gives hard facts about the security track record of phone manufacturers.

ArtTimeInvestor··on It's time for Mark Zuckerberg to resign from Meta

    The CEO is the throughline in a history
    of billion-dollar blunders
Since the IPO, he created an annual ROI of 21% for his investors. Taking risks means blunders are part of the way I would say.

For comparison:

He outperformed the Nasdaq 100 which made 18% (plus dividends) in the same time.

And he way outperformed Warren Buffet who made 14% in the same time.

ArtTimeInvestor··on Why are European countries moving their gold out of North America?
> good luck getting your counter-parties to pay for your exports

It's not a matter of choice. Once a country runs on US artificial intelligence, it can't just say "Well, let's do things manually again". People won't know how to do it anymore. There will be no more keyboards, steering wheels or cash registers to operate.

It's true that China might offer an alternative. But changing a country from being run by US AI to being run by Chinese AI is not a small feat and comes with its own issues.

> US doesn't even produce the chips

TSMC is running and expanding a factory in Arizona. Budget: $265 billion. Intel, Samsung and Miron are also building capacity in the USA.

ArtTimeInvestor··on Why are European countries moving their gold out of North America?
> that AI will remain dominated by USA

The USA has managed to dominate software for decades now. Why would it change? Take a look at the current datacenter investments in the USA vs other countries. It looks very much like the USA will even extend its lead.

> why would they want to default on their debts

So they don't have to share the AI profits with foreigners who hold shares in the AI companies.

ArtTimeInvestor··on Netherlands pulls gold out of the US
How is the situation with Bitcoin?

Do Europeans have options to hold Bitcoin in ETFs, ETPs etc that are not storing the coins in the USA?

ArtTimeInvestor··on Why are European countries moving their gold out of North America?
Or Bitcoin. Of which almost half is already under US control.

Anyhow, much of the new currency will flow to the USA if the USA becomes the worlds source of (artificial) intelligence.

ArtTimeInvestor··on Why are European countries moving their gold out of North America?
The USA might hold a majority of the worlds value generation in a few decades. If AI generated in the USA powers everything. Then the USA does not need to borrow anymore.
ArtTimeInvestor··on Why are European countries moving their gold out of North America?
The dangerous situation we are in is that entities outside of the USA hold significantly more US assets than US entities own assets outside the USA.

So if the USA declares "ownership be damned", it would be a net win for the USA.

Or in simpler terms: The USA has been giving out IOUs for real goods for decades. It is now tempting to default on those IOUs. The USA did this before. Up until 1971, a dollar certified a claim to gold. Then the USA simply canceled that promise.

The current ramp up to AI dominance might be what holds the USA back from breaking more ties with the world. It is a race that must be won. And investments from abroad help. But when the whole world is operated by US AI factories things might look different. When every task around the world is performed by intelligence generated in the USA, just like every computer is run by US software now - there might be little incentive left to "pay the rent" for the rest of the world that now sits around idle, fiddling their thumbs.

ArtTimeInvestor··on Show HN: Ballet – Workflow automation that writes integrations against any API
I don't get what this is about.

The examples they show are someone typing something into a prompt and then some agent starts coding.

But the hard part in automation these days is not writing software. It is "how does the software get the credentials to access data and services? What APIs does it use?". So before being able to type a prompt and then use the software created, there must be the hard part: Setting up all those interconnectivity pieces. Making sure the software can access and change data, trigger actions, but only within a certain scope.

ArtTimeInvestor··on Software Giant SAP Stops Most Travel and Hiring Because of AI's Soaring Cost
It will be interesting to see if SAP can turn into the basis for companies that use AI heavily or if companies that use AI heavily will prefer to replace SAP.

Who are the contenders that start fresh with focus on AI?

One that comes to mind is IONOS. They seem to be in the process of building something like a "SAP in the times of AI" from the ground up. Starting with the demands of SMEs. It looks like an interesting approach to me: Having a "knowledge base" for each customer, initially filled with the data from the website. Then let the customers add more data. Then offer agents that do work for the customers. Answer calls and emails and do marketing for example.

ArtTimeInvestor··on OpenAI's Ad Business Is on Pace to Miss Its Own Forecast by 90%, Analyst Says

    Emarketer’s data finds that standalone chatbots like ChatGPT,
    Microsoft Copilot app, Google AI Mode, and Amazon Alexa for
    Shopping (formerly Rufus) in U.S, will generate less than $1
    billion in ad revenue this year, and just $5.41 billion by 2030.
How would that be possible? In the past I used Google maybe 10 times a day with a short query. From which Google had to guess my intent. Now I babble with Gemini all day about everything. And Gemini can ask questions what exactly I mean. Why wouldn't Alphabet be able to generate more revenue from this than from search? And Google's ad revenue from search is over $100B per year.

Just because there are no ads now does not mean there never will be. Google search was run without ads for the first years too.

ArtTimeInvestor··on An update on residential proxies and the scraper situation
Thats why I said proof of work that is used to mine a cryptocurrency to pay the bills of websites that serve information.

As long as the website gets paid more than the cost of serving the pages, it does not matter if a human or a bot did the POW.

Securing signup forms is another issue. Maybe related. But not what I was referring to.

ArtTimeInvestor··on An update on residential proxies and the scraper situation
In theory, proof of work that is used to mine a cryptocurrency could be a solution.

Bitcoin and others are already secured via massive pow computations. If we could shift that into browsers, no additional energy would be used and we could solve an issue that has been unsolved for too long: How to pay websites that provide useful information other than with ads.

The question is which resources typical consumer hardware has that large centralized compute power does not. In-browser POW to pay websites would only be possible if such a resource exists.

I am not familiar with the topic, but maybe CPU power and memory? Both seem significant in a typical consumer device.

Napkin math: If a consumer device can generate $100 per month, that would be 100/30/24/60/60=$0.00004 per second. If the user waits for 5 seconds before the first pageview, that would then make the website provider $0.0002 per visitor. Serving a million visitors per month is nowadays easily possible on a $10/month machine. So the $0.0002x1000000 = $200 would make the website a nice profit.

ArtTimeInvestor··on France's government is ditching Windows for Linux, says US tech a strategic risk
It is a step into the right direction.

Over time, more and more work is going to be done by AI though. At some point, it will be unthinkably slow and expensive to let humans work on anything.

To do *that* locally, you need GPUs and LLMs.

How will Europe solve these two?

ArtTimeInvestor··on What Drives Stock Market Returns? (2018)
I don't see anything that looks like a "slowing" in mid 2018.

Growth in Q1, Q2 and Q3 2018 was higher than anything that came before.

ArtTimeInvestor··on Bitcoin tumbles below $70K, heavy losses in cryptocurrencies in last three weeks
In the limit, that would mean that Bitcoin's volatility reflects only the savings rate of people.

That would mean that Bitcoin is pure monetary value. In that case, it would suck out all the monetary premium from other assets like real estate, equities and gold. The monetary premium in those is probably a few hundred trillion. So by that time, Bitcoin's price should be 2 orders of magnitude higher than today.

ArtTimeInvestor··on Bitcoin tumbles below $70K, heavy losses in cryptocurrencies in last three weeks
So a minus of about 45% from the all time high three months ago?

If this is it for this cycle, that would indicate the volatility of Bitcoin went down significantly.

Taking a look at the Bitcoin to USD price chart, I see roughly these numbers:

2013: $1,100 -> $238 = -78%

2017: $19,000 -> $3,500 = -82%

2021: $68,000 -> $16,000 = -76%

It will be interesting to watch if the volatility really stays this low suddenly. If so, one could point to the institutional adoption over the last years as the reason for this. When I ask Gemini for the number of public companies with Bitcoin on their balance sheets over the last years, I get:

2023: 67

2024: 79

2025: 190

And a similar trend for Bitcoin ETFs and ETPs. Twice as many in 2025 than in 2023.

ArtTimeInvestor··on Euro firms must ditch Uncle Sam's clouds and go EU-native
AI will be involved in all processing of data. Everything that is human work today will be done by AI tomorrow.

So if Europe will rely on US AI infrastructure, nothing is won by moving the old CPU bound processes off of US cloud infrastructure.

ArtTimeInvestor··on Euro firms must ditch Uncle Sam's clouds and go EU-native
Can Europe build AI datacenters though?

Europe has no wafer production and no companies that produce GPUs.

That means it is dependent on Taiwan for wafers and the USA for GPU design.

Then there is the question wether there is a will to invest. Gemini gives me this list of publicly traded companies in the US and what they invested in AI infrastructure in 2025:

    Amazon: $100B
    Alphabet: $90B
    Microsoft: $80B
    Meta: $70B
    Tesla: $20B
For Europe, I get this list:

    Deutsche Telekom: $1B
ArtTimeInvestor··on ASML staffing changes could result in a net reduction of around 1700 positions
Google is still the best search engine. YouTube is still the best video site. Android is still the best operating system. Chrome is still the best browser.

And on the side they built the best AI and the best autonomous ride service.

Not bad for a "hollow shell" of a company.

ArtTimeInvestor··on ASML staffing changes could result in a net reduction of around 1700 positions

    I've never seen a company that ...
You have not seen Alphabet, Apple, Microsoft? Where are you looking? They all did tens of billions of share buybacks every year for many years now.

Example: Alphabet has started share buybacks in 2015 and increased those every year. $70B in 2025 alone. And they are firing on all cylinders product-wise.
