Very interesting! I respectfully disagree on the complaint about Spark not helping with the security budget as it tries to reduce on-chain transaction footprint. I see it as a scaling solution and I'm not worried at all that miners will get in to problem with their funding. I'm glad the 2017/2018 mempool situation is over now (for now). We should however focus on people not keeping their live savings on exchanges. That's where the transactions should come from.
"during the fork war we all agreed on what bitcoin *was*"
I remember it completely different and have a strong feeling most big blockers at that time feel different about this as well.
Not yet, might create one. There should be one right?
This video by Nic Laporte shows how the surrounding of Arnhem Bitcoin City is seen by a foreigner. Great to see this as a local. (Not a bitcoin video, but very enjoyable nonetheless) h/t nostr:nprofile1qydhwumn8ghj76twdejhytnnv43xzum5d9uzuum0vd5kzmqpp4mhxue69uhkummn9ekx7mqqyqrx8x3cdjwpq9ppwc3ve085pyyvfudqcvlz87xk668540m9t78hzh692k6

Who will join us on the summer edition of the BitcoinWalk Arnhem?
I can't add a site on my phone, county selector does not work. I wanted to add www.stroreofvalue.eu
Great initiative!

The Dutch bitcoin companies have won a lawsuit against the regulator.
Good to read that the lawsuit against DNB (the Dutch central bank) has been won on appeal. I actively contributed to this at the start in my former role as chairman of the United Bitcoin Companies Netherlands (VBNL). Winning a lawsuit against a party who's main job is to make sure everyone is compliant is a *huge* thing. However, the damage is done; Some companies are gone already.

Will I see you at the next Bitcoin meetup in Arnhem?
If you want to join for dinner at the pre-meetup then please RSVP:



I broke open an old piggy bank and found foreign currency left over from holidays abroad with my parents as a child.
I don't remember how I got this specific piggy bank as I've never been a customer of "SpaarBank Rotterdam".
Stay up, don't give in to the sleep. Hate it though. Or is the problem you still wake up at 3:40 am?

Thank you! Interesting to read. So El Salvador can keep their current BTC but are not allowed to gain BTC. Is this denominated in USD or in BTC?
Having been to Berlin, I love seeing this video of Joe. It really is a great place with so many awesome people involved.
Excellent musical taste!


Bitcoin Pizza Day in Arnhem. First pizza dinner at one of the 3 pizzerias that accept bitcoin here (remember all the merchants are saving the bitcoin in Arnhem, no instant conversion).
After that we had a debate about OP_RETURN where I took Oceans/Knots side and nostr:nprofile1qyx8wumn8ghj7cnjvghxjmcpz4mhxue69uhk2er9dchxummnw3ezumrpdejqqg8g6e7yxkj2tycyu9q59q8f2th7z7lyy48u5fu3d0mrl8mnu49t5s02kql2 defended Bitcoin Core's side (we could have changed positions). It was very educational and fun to see how Aaron gave in after my final argument 😂
Friendly reminder for tomorrow!
17:00 Pizzadinner at De Pizzabakkers
19:30 OP_RETURN debate at Foodhall
I believe you did your part Ralph, for instance, Hijman Ongerijmd is now also accepting bitcoin. If I'm the only one spending bitcoin in Arnhem, the project would not have existed today. I understand how you feel, but hope you change your mind well before a decade passes :)

Molly White is my favorite crypto critic. I wish I could zap her some sats.

Awesome newsletter.

I've just watched the Netflix documentary Cyberbunker and I'm surprised to learn I bought my first computer (486DX2-66) at the shop in Arnhem of the main character of the documentary. It's an awesome docu about a very intriguing story.
Why do you feel the need to reset your brain?

I'm in Paramaribo now, and got this taxi driver to install a lightning wallet. The guy once ran into OneCoin and was a bit reluctant but still want to give bitcoin a try.
Feel free to "zap" him some sats 👍

Thursday 26 February we'll have another Bitcoin Meetup in Arnhem!
Want to join for dinner? Please let me know so I can change the reservation at Meem restaurant.

Mocht je daadwerkelijk naar Curaçao gaan check dan zeker even de lokale bitcoin community daar. www.btccuracao.com

BitKassa helped Etos Rokkeveen (Zoetermeer) to accept #bitcoin. Who will be the first to pay with bitcoin here? (I'd love to see proof of it)
Unfortunately no, I don't have an idea why :(

Who will join us on the winter edition of the BitcoinWalk Arnhem?
Saturday January 18th 10:30am. We'll have lunch afterwards at Le Grand Cafe (bitcoin accepted there)
