'Keynesianism or the Chicago school, whatever you call it.' Smh Knut. Monetarists and Keynesians don't exactly get along...

@npub1rxysxnjkh… Nathan did an excellent job with this interview. Simply cannot have enough reminders of the corruption and evil of the Covid regime

Re:other nodes and making news, you're clearly not watching Eric Voskuil on Twitter. Libbitcoin 4 just did IBD in 14 minutes on a consumer connection (with assumevalid height of 950k) and 55 min for full validation. Older than Knots, and older than Core being called, well, Core. They slept for a good few years but are waking up with a vengeance.

One of the best episodes I’ve listened to in a while. Great bear market content. This makes me want a family more than I already do. @npub10qrssqjsy…

This is sweet, thanks for covering this. Been getting excited listening to @npub1v25jqj332… talk about Stratum v2 for a while now. Nice to see it in action.

The cloak and dagger shit with Switck is heating up. People were already looking for a reason for this to be inside. Still not totally convinced but it looks sketchy as fuck. Never been more glad I had fun playing dice games with my bitcoin.

One of the best WBD's yet. Dines' coverage of the Eurodollar mechanics here and the shift that happened with LIBOR to SOFR is something far too few people are talking about (Luongo notwithstanding).

I’ve missed this Saylor. I watched a 2020 interview of his last week and it reminded me of the excitement and well-roundedness of this man. Digital credit is fascinating, but I would much much rather listen to him riff on Rothbard.

Your analogy is odd given that the twentyfirst amendment struck the 18th amendment from the constitution... The issue with 110 is that it was ineffective and targeting an issue that barely qualifies as one. 4 MB is 4 MB.

The point of airgapping isn't that QR'sbor SD cards are inherently more secure than USB or Bluetooth. It's that the amount of data is far more limited and easier to audit with lower tech methods. If you ask me floppy disks would be even better, as SD cards have firmware that could be an attack vector. But floppies are prohibitively hard to implement in 2026.

'Anything is safer than a coldcard' is not entirely accurate, especially if you're one of the fence cases. Malware hot wallets are having a field day. Saw one user lost 6.07 BTC on mobile 'wasabi' wallet which of course was fake.

I'm thinking the four year cycle is not as there as some have said. Stephen Perrenod has some great writings and math to go with it on some harmonics describing oscillations around the power law trend that seem to make more sense when thinking about fundamental factors. And it follows log time, with the last peak in 2017 and the next in 2027. There are sub harmonics, hence oscillations in between. The fun thing is, it captures the 2011 run up too...

So glad we finally got some weigh in here on the silliness that is 110. And yea, probably was a low blow last time I asked you about this topic on zoom Natalie...

Someone's out to capture Bitcoin all right. It's the ones who are running thebonly implementation and mining pool that supports this dumbass fork. They're just a lot more retarded than even Bcashers, with a single percent of blocks in any signalling period so far with only 2 to go. Most don't know enough about Bitcoin to realize how cooked they are though. And the ones who do are too sour to do anything about it. Have fun storming the castle.

I gotta say Rustin, I'm pretty disappointed in the portrayal of spam being about data space. That is hard capped at 4 MB/block. Being opposed to using that space is to be opposed to Bitcoin being used. Spam has other issues, sure. But the size on nodes is Simply noise.

Just gonna point out as a non-MSTR lover that $82.50 with 11.50 in annual dividends is a 13.94% yield. So when you say STRC hasn't done well but SATA has it's a bit weird as they're trading for the same yield...

Owning Bitcoin and buying Bitcoin are no longer counter culture. Spending it and accepting it as a merchant still are. Best part is, it makes the orange ties cry. It's a place they can't follow.

    This was a very helpful overview of Bitcoin technicals. We probably need to start including things like this in early Bitcoin education

    Some of the best presentation of the issue I've encountered. Education not recommendations. The multisig evangelists are dangerous, and the guy who hosts the exchange is telling us to self custody. Man of the People @npub1cn4t4cd78… .
