@JoelKatz @BlueHorseshoeKF @em_Lazzy Your life is inefficient, and almost all things in it can be done another way.

[Dimitar Pachov @dpachov]

@paulg @RoKhanna Oh, Paul, you can't be so naive.

Yes, it is. Why? For instance, "growing fast" implies investment, & that investment comes from accredited investors, & these investors further increase their wealth by "hoarding" their wealth in your startup, while actively helping it grow.

[Dimitar Pachov @dpachov]

The message may be right but the examples are terrible.

I'd like to see top scientists in universities on O1 or H1B.

Russians don't have anywhere to go - really, even *without* this DHS move do you think Ukrainians have a place to go, hello?

[Nick Davidov @Nick_Davidov]

The biggest bullshit move by DHS in its history. So everyone on a O1 or H1B visa would have to stop working legally in the US, go back to their country and wait for years of backlog? This includes top scientists in our universities, founders of billion dollar companies (at least 3 just in our portfolio would be affected by the way). And if we look at individual countries it becomes even more bs. Indians would have to wait decades. Russians don’t have anywhere to go (there is no US embassy in Russia, hello?).

This is the worst imaginable way to disrupt important work for the country and pretend you’re fighting some loophole.

[Dimitar Pachov @dpachov]

What he refers to is the memorylessness of Markovian property. However, if agents work with known & defined timescale boundaries and take actions falling within their limits, the percentage of usefulness can be much higher.

As an analogy:

[François Chollet @fchollet]

Most human tasks are not Markovian, the optimal next action cannot be determined solely by looking at the current state. It depends heavily on the past trajectory, the original intent, and context constraints. An agent that cannot compress and track its past trajectory with absolute fidelity is maybe 20% as useful as one that can.

[Dimitar Pachov @dpachov]

Yes, because Southern & Eastern Europeans have genuine emotions expressed naturally rather than using corporate, politically correct, PR-firm legalese.

[John Paul Newman @johnpaul_newman]

In Bulgaria they don't say 'Congratulations Dara on your historic Eurovision win for Bulgaria', they say 'Bravo Darche you fucked their mother bravo' and I think that's beautiful.

[Dimitar Pachov @dpachov]

Rasmus is usually okay but obviously describing to a conservative retiree how the young-ish world functions is an Everest-climbing mission.

He has forgotten he used to be young surrounded by a galore of quite *similar* things, just in a different dimension.

Not a cool take.

[Rasmus Jarlov @RasmusJarlov]

The closest I will get to admitting to MAGA people and other Europe haters that Europe is ridiculous is when I see the pictures from the Eurovision. I used to enjoy it a lot when I was a kid back when it was a music contest. Why have normal Europeans allowed it to turn into this freak show?

[Dimitar Pachov @dpachov]

Sorry, but people are stupid.

"The "Z" on Russian military vehicles is a pro-war propaganda & identification symbol used for the invasion of Ukraine. It has absolutely NO connection to the fictional hero Zorro, who uses a "Z" as a MARK OF JUSTICE & DEFENSE AGAINST OPPRESSION."

[Oksii ✚ 🇺🇦 @Oksii33]

Emm… this photo is posted (December 2025) by a Bulgarian singer, who won the Eurovision 2026. Don't even try to tell me that she didn't know the meaning of this symbol and didn't mean it, she meant…

@archer_rs I know not a single person who rides motorcycles or cares about any result related to motorcycles.

Bulgaria 🇧🇬 Eurovision 2026 win:

"... the biggest winning margin we've ever seen at the Eurovision Song Contest ...".

Bangaranga situation!

Yeah, I know the world outside of Europe doesn't care , but Eurovision 2026 goes to ... Bulgaria 🇧🇬!

Rarely does Sam tell truth but here it is: Elon has always been, is & will be oblivious about what "research" is.

Elon's long-term damage to humanity will be measured in many, many years down the road. Oh, don't please refer me to Tesla & SpaceX - I said "humanity" & "long-term"

[Alex Volkov @altryne]

Sama during trial: "I don't think Mr. Musk understood how to run a good research lab"

Q: How did Musk's management affect OpenAI's research culture?
Sama: "He had demotivated some of our most key researchers... required Greg and Ilya to make a list of the researchers and list out their accomplishments and sort of stack rank them... I take a chainsaw through a bunch and that did huge damage for a long time to the culture of the organization... this idea that you constantly have to show your results and if they're not good enough on a short period, you're going to get fired... that really didn't work for the kind of research we went on to successfully do."

[Dimitar Pachov @dpachov]

@ChigaCzr 4:2

[Dimitar Pachov @dpachov]

Hahaha. "You don't have to do anything bad to make a company grow fast."

Paul, Paul, such wishful thinking. So you want me to provide a list? Let's start by ... Uber.

Give me a start up that "made it" & I'll tell you the bad. Deal?

Will you be silent instead?

[Paul Graham @paulg]

Sure you can earn a billion dollars. I've been teaching people how to do it for 20 years. The way you do it is to start a company that grows fast. You don't have to do anything bad to make a company grow fast. You just have to make something people want.

Translation: We did everything we could to elect Trump & line our own pockets. Since the payout fell short, it's time to throw some scapegoats under the bus.

Brian's "mission-focused" company free of politics: he just forgot to mention the mission was lining his own pockets.

[Brian Armstrong @brian_armstrong]

This is an email I sent earlier today to all employees at Coinbase:

Team,

Today I’ve made the difficult decision to reduce the size of Coinbase by ~14%. I want to walk you through why we're doing this now, what it means for those affected, and how this positions us for the future.

Why now
Two forces are converging at the same time. We need to be front footed to respond to both.

First, the market. Coinbase is well-capitalized, has diversified revenue streams, and is well-positioned to weather any storm. Crypto is also on the verge of the next wave of adoption, with stablecoins, prediction markets, tokenization, and more taking off. However, our business is still volatile from quarter to quarter. While we've managed through that cyclicality many times before and come out stronger on the other side, we’re currently in a down market and need to adjust our cost structure now so that we emerge from this period leaner, faster, and more efficient for our next phase of growth.

Second, AI is changing how we work. Over the past year, I’ve watched engineers use AI to ship in days what used to take a team weeks. Non-technical teams are now shipping production code and many of our workflows are being automated. The pace of what's possible with a small, focused team has changed dramatically, and it's accelerating every day.

All of this has led us to an inflection point, not just for Coinbase, but for every company. The biggest risk now is not taking action. We are adjusting early and deliberately to rebuild Coinbase to be lean, fast, and AI-native. We need to return to the speed and focus of our startup founding, with AI at our core.

What this means
To get there, we are not just reducing headcount and cutting costs, we’re fundamentally changing how we operate: rebuilding Coinbase as an intelligence, with humans around the edge aligning it. What does this mean in practice?

- Fewer layers, faster decisions: We are flattening our org structure to 5 layers max below CEO/COO. Layers slow things down and create coordination tax. The future is small, high context teams that can move quickly. Leaders will own much more, with as many as 15+ direct reports. Fewer layers also means a leaner cost structure that is built to perform through all market cycles.

- No pure managers: Every leader at Coinbase must also be a strong and active individual contributor. Managers should be like player-coaches, getting their hands dirty alongside their teams.

- AI-native pods: We’ll be concentrating around AI-native talent who can manage fleets of agents to drive outsized impact. We’ll also be experimenting with reduced pod sizes, including “one person teams” with engineers, designers, and product managers all in one role.

In short: AI is bringing a profound shift in how companies operate, and we’re reshaping Coinbase to lead in this new era. This is a new way of working, and we need to leverage AI across every facet of our jobs.

To those who are affected
I know there are real people behind these decisions — talented colleagues who have poured themselves into this company and our mission. To those of you who will be leaving: thank you. You’ve helped build Coinbase into what it is today, and I am sincerely grateful for everything you've done.

All impacted team members will receive an email to their personal account in the next hour with more information, and an invitation to meet with an HRBP and a senior leader in your organization. Coinbase system access has been removed today. I know this feels sudden and harsh, but it is the only responsible choice given our duty to protect customer information.

To those affected, we will be providing a comprehensive package to support you through this transition. US employees will receive a minimum of 16 weeks base pay (plus 2 weeks per year worked), their next equity vest, and 6 months of COBRA. Employees on a work visa will get extra transition support. Those outside of the US will receive similar support, based on local factors and subject to any consultation requirements.

Coinbase prides itself on talent density. Our employees are among the most talented people in the world, and I have no doubt that your skills and experience will be highly sought after as you pursue your next chapters.

How we move forward
To the team that is staying, I know this is a difficult day. We’re saying goodbye to colleagues and friends you've been in the trenches with. But here’s what I want you to know as we move forward together:

Over the past 13 years, we have weathered four crypto winters, gone public, and built the most trusted platform in our industry. We’ve made it this far by making hard decisions and by always staying focused on our mission. This time will be no different – nothing has changed about the long term outlook of our company or industry. And most importantly, our mission has never been more important for the world. Increasing economic freedom requires a new financial system, and we’re building it.

The Coinbase that emerges from this will be more capable than ever to achieve our mission.

Brian

@timwido @RnaudBertrand Give me examples of any entity in the 21 century that has been fully prepared for everything thrown at it. Include personal instances, if you wish.

[Dimitar Pachov @dpachov]

@timwido @RnaudBertrand Fail safes for unexpected wars, madmen in various countries, global epidemics, technologically-enabled propaganda, etc at the same time?

I also wasn't commenting on general geopolitical situations but rather on the specifics of the original post. Conflating topics doesn't work.

This oblivious guy can't realize he is going to have the same cultural shock by visiting some coffee shops Palo Alto, Bay Area, Silicon Valley, US. 🤫

[Alex Recouso @recouso]

Okay guys, had a few cultural shocks in Spain:

> Go to the gym, opens 10am on a Sunday
> Go to work from a coworking, closed
> Go to a coffee shop, no wifi

Absolutely unthinkable in a barely productive economy like the US, yet alone UAE.

Europe is a daylight museum.

[Dimitar Pachov @dpachov]

Mar 2025 --> Mar 2026 Inflation

- United States 2.4% --> 3.3%
37.5% increase

- Bulgaria 4.0% --> 4.1%
2.5% increase

Sure, it's because of the Euro. The anti-EU propaganda has no end.

[Steve Hanke @steve_hanke]

Bulgaria’s inflation EXPLODED to 7.1%/yr in April from 3.9%/yr in March.

As the Father of Bulgaria’s currency board, I predicted an inflation SURGE with the introduction of the euro.

EURO INTRODUCTION = BAD MOVE.
