Feels like bitcoiners are finally pushing harder for real world usage of bitcoin 🔥

Let’s meet today on @BTC Prague 🔥 
Today I will have a nice panel session with @BTC Map master - @Nathan Day 🚀 Who knows where the discussion will progress, but I would like to discuss mainly bitcoin adoption. Examples what works and what doesn’t. Hope to see you there 🫵

Proč je výhodný platit bitcoinem? Koukněte na přednášku z Cryptobyte na téma bitcoinové adopce. 🚀

Why do bitcoiners tend not to pay with bitcoin? Making a bitcoin transaction with an “ordinary” person often seems surprisingly easier to me... #asknostr

Don’t miss the chance to visit Zlaté Sele during your @BTC Prague trip.

73 years ago on this day, politicians robbed the people of Czechoslovakia through the so-called currency reform. Overnight. Today they're smarter and do it gradually.

@Juraj is building AnyPay - service to pay any crypto request with ⚡️lightning.

AnyPay: Pay any sane QR code

Scan or paste a BTC, ETH (including L2s), SOL, LTC, XMR, ZEC, or DOGE address — your Lightning wallet covers it (including stablecoins). No account. We don’t have custody, we are only a frontend. Support provided by the swap services used, not us. We just find a way to pay it.

Using KYC is very dangerous. And paying taxes too...

@Egge do you have some plans with npub.cash? It’s super useful tool, but development seems to stopped?

Exactly. Most people don’t understand opportunity cost. View quoted note →

Let's meet on https://pizzaday.cz/ - I will have a workshop on @Linky project there tomorrow.

Now with seamless migration from legacy labeling that was dependent on Google or Dropbox. 🚀 View quoted note →

Come to Prague in June and don’t miss Freedom Tech Summit (powered by @vexl 😎 , event formerly known as dev/hac/day). It’s a highly inspiring and interactive event for people interested in building within the #bitcoin, #cashu, #nostr, and other self-sovereign technology. I’m very grateful that this year I’ll also be giving a short workshop introducing the @Linky project. 🎉

Satoshi can reveal himself at any time simply by signing a message. Maybe his fingers itch somewhere and he occasionally feels like doing something like that. But quantum computers might make it possible for anyone to eventually create such a signature. In that sense, we will all truly become Satoshi. And finally relieve him of that burden. #weareallsatoshi

Not having control among others is blessing.

@Cashu is great for sharing bitcoin with people who don’t yet have any bitcoin or even a bitcoin wallet. However, when I compose a specific denomination, it ends up being a lot of tokens - in other words, a very long URL that I’m trying to use. The web URL is so long that messaging apps often don’t even recognize it as a link… and it can even look a bit like a scam. In printed form, I can’t use animated QR codes. I understand that using powers of two has many advantages, such as privacy or simpler splitting and merging. However, wouldn’t it make sense in some cases to create one-time exact denominations? Or to keep it composed of many tokens, but allow the mint to temporarily group them into a single alias? Since there is already trust in the given mint, it feels like this wouldn’t introduce additional risk. What do you think? @calle ? 🙏
