Club Orange turns 4 today! 🎉 4 years of meetups, friendships, and Bitcoiners finding each other! Thank you for being part of it. 🧡 And to celebrate, we're giving away 4 lifetime memberships! Tag a Bitcoiner who could use more friends. The 4 with the most mentions win. ⚡️

the rotation from AI to bitcoin is going to be monumental

Here's some fuel for all the Europoor haters: Germany just told us we'd have to fire one of our 3 founders to qualify for funding. I was in talks with a German state-backed fund of fund managing billions, with one single mandate: invest in German funds to drive innovation and economic growth in the country. They literally told me they like us a lot and are also impressed by our track record and performance so far, and even though not everyone in their team is a fan of our thesis, they believe in it. But they passed for a whole different reason: Because our all-male team of 3 people isn't "diverse enough" lol. they literally told me: hire two more female partners (impossible on the economics of a fund our size), or let one of the three of us go to make room for a quota hire. do that, and they'd strongly consider investing. I won't even get into how discriminatory this is toward men in the first place. nobody takes that seriously anyway, and honestly I don't care. but what actually gets me is something bigger: as a German, I have to face the fact that the whole world continuing to laugh at Germany and overall Europe is completely justified. a system that quietly kills the smallest, hungriest teams, the exact ones this money was created to support. and then everyone acts surprised that talent and capital keep leaving the country.

If you really understood Bitcoin, your allocation would be 100%

Tldr: Customers who deposited money into Peter Schiff’s bank “may end up losing 100% of the value of their accounts.”

france is the leading country on the planet for crypto kidnappings and wrench attacks largely because their tax authority leaked the personal data of everyone now they want to increase by 50,000x the amount of data they collect and hence leak zero

This Ledger hack is just about the same size as the Coldcard hack ($93M vs $110M), but the Bitcoin Twitter response is less than 1% of what we saw during Coldcard. Why so drastically different?

This is @saifedean at his best. Fiat educators still haven't recovered from this.

Higher rates inject more money into the economy, that money gets allocated to equities, and the effects of passive management drive valuations higher.

Surprised at the reaction to this post. Here is the thought that generated it: 1. I logged onto Coinbase recently to buy more BTC, & was struck that unlike when i first bought BTC on Coinbase in 2013, Coinbase now offers all sorts of BTC derivatives, offering varying degrees of leverage, all cash-settled (not BTC-settled). 2. BTC peak-to-peak CAGR returns have collapsed in the 2 cycles since cash-settled** BTC derivatives began trading (**"cash-settled" is key, because it means the owner of the biggest printing press increasingly sets marginal prices over time, NOT physical supply & demand. In most cases, the owner of the biggest printing press is the very fiat system BTC was designed to escape from) 👇 As a BTC holder since 2013 (and still), this collapse in peak-to-peak CAGR of BTC troubles me greatly. I would be happy to have anyone explain why peak-to-peak returns have collapsed in the past 8 years & why they think this trend will stop despite the seeming continued expansion of cash-settled BTC derivatives and cash-settled betting markets on BTC. Thank you. 🙏❤️

1/ How I infiltrated a Chinese organized crime syndicate that has laundered $1B+ across multiple exploits for Lazarus Group. Posing as a client, I gathered intel that helped action freezes for the Feb 2025 Bybit exploit and attribute illicit activity onchain.

awa tier list more or less like this the good coins have been quite consensus for a while but winners average winners lots of defi coins in mid-tiers because although investable they usually don't have a ton of trading volume cointierlist.xyz/

Full post-mortem of the September 19 attack, and a 50% bounty — up to 3.3 BTC — on the stolen funds: blink.sv/blog/sept-19-attack… Bounty terms: blink.sv/bounty-terms On Saturday September 19 an attacker used a flaw in our admin tools to take over 35 Blink accounts and withdraw about 6.61 BTC from 24 of them. A customer called one of our engineers at 11:39 UTC. Fifteen minutes later the whole custodial service was off. By that evening the hole was closed and the service was back. By Thursday September 24 every affected customer had their exact balance back, in bitcoin and in dollars, paid for by Blink's shareholders. No customer bears any loss. This was our fault. Not Bitcoin's, not our users'. To the 22 customers whose bitcoin was taken, and to the 3,817 people whose account details were looked up: we are sorry. How it happened: From October 2023 until that Saturday, anyone with a free Blink account and a web browser could give themselves the powers of our support staff: change the email or phone on any account, log in as that customer, raise their limits. Three unremarkable mistakes in how our admin tools checked permissions, stacked on top of each other, in code we inherited. The whole team was busy moving tens of thousands of users to self-custody under new regulation. Monitoring built to catch outages didn't catch an administrator doing things no administrator should. What it didn't touch: The money came out of our hot wallet. Most customer funds sit in multi-signature cold storage that nothing in our admin tools can reach. Non-custodial accounts were never in play: we don't hold those keys. What the attacker saw: They also read the details of 3,817 other accounts, in some cases a phone number or email address. Not names, not IDs, not addresses, not passwords, not seed phrases. We wrote to every holder we could reach, saying exactly what was seen. What stopped them: Two-factor authentication. The attacker logged in to nine accounts that had it on and tried eighteen times to move money. Zero loss. None of the 24 drained accounts had it on. If you take one thing from this post: Settings → Security and Privacy → Two-factor authentication. Then turn it on for your email too. What we changed: The flaw was fixed the same day and a third layer added two days later. The admin tools are off the public internet. The functions that change a customer's email or phone are switched off for everyone while we redesign them. All customer API keys were revoked. The hot wallet now holds a fraction of what it did. Security fixes are developed privately and published once deployed; the code stays open source. A standing security reporting channel is live, with rewards of up to 0.1 BTC for critical findings. Where the money is: Some still sits where it was withdrawn to. About 5 BTC has gone through a cross-chain swap service; a small amount reached an exchange that is cooperating. Criminal complaints are filed in El Salvador and Próspera, the regulators are notified, and we have traced the funds continuously. We are not expecting the money back. So we are putting a 50% bounty on it. Whoever provides the information that leads to a recovery gets 25% of what is recovered. Another 25% of anything recovered goes to Bitcoin Beach, Bitcoin Ekasi, Afribit Kibera and the circular economies they choose. No cap, no end date, paid only out of funds that actually come back. Write to [email protected]. We would far rather have spent this money on grassroots Bitcoin adoption than lost it to a thief. Shame on the attacker. One more thing: Ignore any email or SMS about this incident that contains a link: we contacted affected users only through messages in the Blink app. We will never ask for your PIN, password, seed phrase or a login code. The full post-mortem has the timeline, the technical detail for anyone running code derived from ours, and the bounty terms (links at the top).

I recently learned my neighbor's daughter gives maths lessons to children in the building for €5 an hour "It's a symbolic amount, and these kids really need it" my neighbor said I gasped In Europe you cannot conduct economic activity without a registered business and a VAT number I reported it right away on Monday morning The entire family was audited for the last three years It turned out the mother had been illegally reselling secondhand clothes online without registering to VAT They owe €12,000 in undeclared income and penalties It is frightening that you never know if you are living next to criminals
