Why the hell are we doing all this here and not in another podcast?

There is a market that wants to adopt and use the Bitcoin protocol but its voice is so faint that it can’t be heard over the status quo.
That market will grow when more people resonate with it - not through moral resonance but something deeper and more meaningful - the type of resonance that compels action.
I strongly believe this market will amplify over time but it will be very slow and we won’t notice it getting louder for some time.

If Bitcoin is dependent of its adopters to be moral - I think it’s doomed.
It’s supposed to transcend the need to trust the morals of your counterparties

I like this - but there’s a fork that determines if one is accountable - you’ve presented the accountable case:

This is why purity tests are the wrong tool - markets are the tool.
This is a state change in Bitcoin’s culture that is playing out with the fork episode

The market is showing a preference for value that is transcending the natural urge to corrupt the market.
It’s overcoming gravity.

When immoral acts dominate markets, the markets typically devolve to irrelevance.

2026-07-14 22:44:58 UTC

- reply

It’s clearly immoral to rug people and deceive people. This isn’t inherent to markets - just like people can do immoral things when they have the freedom to. Doesn’t mean freedom is immoral.

It’s not a deadly bug. It is an emergent consequence from a problem that was solved at the time with the best thinking available.
It is far from deadly. Many people are working on solutions like witness pruning for example.
But just think about what you would have to believe just to view what Segwit allows for now as deadly.
I do think it is damaging that people can abuse the discount. There will be solutions. They will be better than v30 when we can communicate better with each other.

It’s not a fallacy to think that Bitcoin might succeed as an immutable money.
But most people are highly mistaken that it’s already the case.

Bitcoin users won’t survive a society imposing purity tests. Valid Bitcoin transactions are the purity test. That’s the beauty of it.
The rest is up to the users to be the best possible versions of themselves. Some of us might survive the next 10 years.

2026-06-08 12:58:37 UTC

Bitcoin is not inherently immutable.
It’s going to be a long process to co-opt humanity into making it immutable, largely by attempting every possible way to change it.
Humanity needs to determine what is immutable about ourselves before we can have a shot at having an immutable money in our rear view window.
We must evolve and upgrade ourselves to it. Understand the protocol and also understand yourself.
Nobody will do this for you and Bitcoin will no longer “moon” for us as we currently are.

Mathematics is a pathway to God.
Certainly "doing math" is not. But learning it for its own sake - for no other purpose than to get closer to God - not ever asking "why do I need to learn this?" or "what advantage will this knowledge give me" =
Getting closer to God requires dissolving yourselves of the notions of gaining advantage through knowledge. If you can spend an hour learning for no other purpose, you build a skill that is surely useful towards getting closer to God.
Understanding God as the identity element of an algebraic structure has potential implications and insights whose exploration paves a clear pathway to his divine presence and wisdom.
Such a structure always has an inverse element, so any action you might do that takes you away from god always has an associated action that can have you return. This is the highest learning that algebra has ever taught me, though understand cryptography and building conviction in Bitcoin is a nice result as well.
i'm beginning to think that all paths that include Bitcoin being successful have man understanding God as a first boss. Bitcoin is pointless outside of God's context. You wanna end the Fed? What do you think will replace it outside of God's context?

Every Bitcoiner should familiarize themselves with the term “Mark to Model” before they try and understand too hard how the world operates.
Mark to Model is the intellectual dead end that killed the last remaining intelligent remnants of TradFi
Bitcoin cannot live in a Mark to Model world. This is why the capital rules treat us with such draconian impunity.
Trust me that we do not wish for this to change

There is a fiat institution, yes, but there is an institution of a marriage that lives beyond that realm.
Perhaps it lives in the realm of God. Bitcoin will both challenge the conventional bases for marriages and provide the access to God that will be needed to navigate through them.

I assure you that whatever the real data is - Bitcoin will increase the divorce rate significantly in the next 50 years.
Bitcoin will wreck all institutions - especially relationship oriented institutions - until we figure out how to rebuild them around its existence.

2026-05-30 11:09:03 UTC

Bitcoin is not a think that anyone understands. It is not money. It is not property. It is not any “thing” and you are nobody to limit it to any of these things.
Bitcoin is a clue to a bigger puzzle. The clue is not useful to people who think they already know the answer.
Bitcoin is valuable - ONLY - to people who can acknowledge that they don’t understand what it is and what it’s here for.
Perhaps it’s entire value is to make us inquirers because the people who “think they know” are most certainly NGMI

If you are not hopeful of humanity, you’re not going to navigate owning and HODL’ing Bitcoin very well.
NGU requires no faith in humanity. But getting through your fears of what people will use the chain for and how they will leave it for our descendants requires a strong faith in our better selves prevailing as a species.
Bitcoin won’t alter humanity or fix a God-damned thing unless we allow it to and that requires the utmost faith that humans will make it work.

AI seems a lot like amphetamines. Great to use for a month (or two if you’re really building something new) then take some time off to recover and build real world scaffolding for what your AI did.
