Karma is a b*tch. Our b*tch.

Honestly, I have no idea if I did this right! I flashed a script onto a $15 wireless e-paper tag (the kind used for store price labels) so it displays the BTC/USD price, updating every two minutes. Is it overkill? Probably. Is it beautiful? Absolutely. Is it Bitcoin? Yes. Code is public, repo is open.

GitHub - vaccotti/BTC-USD-E-Ink-Ticker-Heltec-Wireless-Paper-V1.2-ESP32-S3: A minimalist, always-on Bitcoin price ticker using an e-ink display. This project fetches the BTC/USD price and 24h percentage change from Binance’s public API and displays it on a Heltec Wireless Paper V1.2 using an ESP32-S3. The screen refreshes every 2 minutes and retains the last image even when powered off. Don’t trust, verify.

Open source. Everything. If money is just information, this is what it should look like. Stay humble. Stack sats. Build weird stuff. 🧡

A $12 Hardware Wallet? Many people delay using a hardware wallet because of the high entry price. But @Blockstream has something very cool: a DIY Jade flasher that lets you build your own Jade quickly and for free. All you need is a small $9 LilyGO T-Display board. And if you want to make it a bit cooler, you can add a $3 case. Bitcoin is for everyone. Love freely, stay humble, stack sats.

With @adrianbernabeu, talking about Bitcoin as the ultimate collateral at @Adopting Bitcoin . We went deep into the @Firefish case, a powerful example of how real-world Bitcoin finance is evolving and yes, they even have a very cool book you can download for free: Bitcoin:

Bitcoin: The Ultimate Collateral (English book) 🇬🇧

Freedom begins the moment you tear down your mental prisons. Fix the money, free the mind!

Talking about @Bitcoiner Jobs on national TV 🇵🇾. Adoption is irreversible and irreverent, no permission asked, sat by sat. ⚡

The @Satsconf was a high-signal moment, people from all across Brazil 🇧🇷 dreaming the future of Bitcoin, together.

GN! You can try to ‘create culture’ by imposing tools and methods no one asked for. But time, and the greatest arbiter of all, the people, will decide which behaviors align with the future they want to build. The first is coercion, not culture. The second is how real culture emerges: organically, freely, from voluntary adoption. That’s the lesson of open systems. That’s the lesson of Bitcoin.

“It’s rules without rulers. It’s individual liberty." You captured a universe, a story that belongs to no one and to all of us. Pure signal @Avi Burra , thank you for the magic.

Ready for the dip. Stack sats.

GM! Back in the ancient times, when Twitter was still called Twitter and hadn’t sold its soul, we used to call posts “tweets.” Cute. Centralized. Fleeting. But on Nostr? We don’t “tweet.” We broadcast. We zap. We signal. We publish messages that don’t depend on a CEO, a board, or a fragile database sitting in San Francisco. If we really want a name, we call them what they are: Notes in the open. Proof-of-speech. Signals on a sovereign network. Because Nostr isn’t social media: it’s digital freedom with a send button. Peace&Zap

We’re closing an exceptional year for @My First Bitcoin ! Pure high-signal work: more than 75 organizations across 40 countries delivering free Bitcoin financial education to their communities. A global movement powered by conviction, sovereignty, and the simple idea that knowledge, like Bitcoin, scales without permission.

“Bitcoin for Lawyers” in Asunción. Packed room. Orange pills for everyone and a future built on pure PoW.

I’m the unacknowledged son of Musk. He met my mother in Uruguay back in the 90s. Long story, mate. But I’m not here for family drama. I’m here to tell you something simple: X is garbage. Nostr is the future. Stop letting corporate algorithms decide what you see, what you think, and who you become. Fix the money. Fix the comms. Long live Nostr.

Dua and I wish you all a happy Thanksgiving!

E-mail services are… let’s say it clearly: centralized. Tools that act as bridges to onboard more people are valid, but only with the right narrative, not dressed up in poetic marketing fluff. If we’re serious about adoption, we don’t pretend centralized tools are the promised land. We use them as stepping stones, nothing more.

Perfection is the enemy of good. Those who dare to build something imperfect, but improvable, are the ones who actually move forward.

@Fran Finney, last Sunday, in Asunción, Paraguay, we ran in memory of Hal, and all the funds raised were donated to a charitable organization. His legacy continues to inspire us. #Run4Hal #RunningBitcoin

For weeks I’ve been crafting my first novel, a story that exposes a brutal truth: even the most honest, transparent, mathematically unbreakable system humanity has ever created, Bitcoin, is constantly surrounded by frauds who parasitize its legitimacy to build palaces of lies. I don’t want to write this alone. That’s why I created a Substack and a pre-reader club where you’ll get early access to chapters, the chance to tear them apart, improve them, enrich them, and shape this project with me. If you’re a book rat, a relentless reader, and someone who feels Bitcoin in your bones, I’m inviting you to join this beautiful madness. Let’s write something worthy of the truth. Let’s build it block by block. 👇👇Join Us👇👇
