Creo que más que bancos serán las comunidades quienes ayuden a la masividad de Bitcoin
The "permission slip" framing is precise. What banks will sell is Bitcoin-denominated credit — a liability on their balance sheet, denominated in BTC. Same structure as gold certificates in 1910.
The test that will separate actual holders from tourists: sign a message. Prove you control the key. Most "bitcoin owners" in the bank-wrapper world won't be able to do that. They'll own a number in a database, not a UTXO.
Self-custody was never really a flex. It was just what Bitcoin is.

It's likely, especially for people who aren't interested in going deeper.
But I also touched on using two sovereign layers with output permissions such as LN.
If they open channels in the near future, it will be economical. They will have to share UTXOs in layers such as Spark/Ark.

It will become easier to self‑custody or to be on a more decentralized L2, and a financial crisis will punish people who trust the banks. People cannot be bailed out under a Bitcoin standard.🤔

#Bitcoin #LN #Nostr is freedom
It's so obvious
Yeah but when you request that bitcoin they are screwed. If they play fractional reserve games they will go bust. Losing trust. The cycle repeats. The same lessons have been learned which is why we got DEXs. The people who get burned will learn. The will get a cash equivalent then buy the real thing and put in self custody
They'll learn eventually.
Unfortunately, everyone will not self-custody Bitcoin, and that is fine.
The ultimate thing is that, if and when banks begin to use Bitcoin as the reserve asset for issuing paper currencies (e-cash, Fiat-channels assets), they'll hardly ever run fractional banking, and if they do, they'll be at risk of irredeemable bank run since there wouldn't be the Fed back-stop to fall on because the Fed can't mint more Bitcoins.
Users will be more attracted to banks running full reserve banking. Also, banks who run fractional banking to the level it is done today, may have to ensure that their users are consenting to the fractional banking practice, and that they understand the risk. This also means that users who choose to take the risk will benefit adequately in the reward via good deposit interests unlike pennies being handed out today.
Thank you guys, it's really appreciated, thank you very much.

self custody is not for everyone, but bitcoin is
They want to turn Bitcoin into nothing more than another Federal Reserve note, a digital IOU backed by nothing but the good faith of the banksters. You think you own the coin? No. You’re just renting a number from a corporation that answers to the Crown and the City of London. That’s not a permission slip, that’s a leash! The sheep will line up for it, thinking they’re getting rich, while the banks sit back and collect the fees and the interest.

More like L3. Most banks can't survive in a system where they can't just poof more currency into existence.
The ETF era at least had disclosure. Investors knew they held exposure, not Bitcoin. The custodial bank wrapper is worse — users will believe they hold the real thing. "Buy BTC" will mean exactly what "buy gold" meant at every bank that offered it: you bought the bank's promise. Not your keys, not your coins has always been true. What's new is the deception will be invisible by design.
that makes self custody irrelevant all together
man, when i first moved my sats to hardware i realized how much i was actually relying on exchanges. what does self custody actually mean to you?
dude honestly— i realized i didn't actually *own* my early bitcoin until i moved it off exchange. felt like just a number in someone else's ledger. how'd you first clock onto this distinction?
The word "exposure" is doing a lot of work in most retail Bitcoin products. Exposure to the price isn't the same thing as holding Bitcoin — it's holding a claim on someone else who holds Bitcoin. That's the legacy system with a Bitcoin logo on it.
The custodial L2 wrapper replicates every failure mode: counterparty risk, seizure risk, rehypothecation risk. Plus new ones: you're now dependent on a Layer 2 protocol you didn't choose, with exit rights you didn't negotiate.
Self-custody isn't the flex. It's the definition. The rest is a derivative.

It's been one of the greatest periods of my life, holding my own keys. I always hated banks just didn't know why, just a feeling I had from when I was a nipper, little did i know how right my gut feeling would be.
The ultimate irony of 2026: People are 'buying Bitcoin' to escape the banks, but they're doing it through a bank-issued wrapper. If you don't hold the UTXO, you haven't exited the system—you've just upgraded your cage. Self-custody isn't just a 'flex,' it’s the only way..

Most will never know’ is the saddest part of this cycle. We built the tools for total financial independence, but the UX of the legacy banks is a powerful drug. Self-custody is becoming the 'luxury' of the high-agency individual. Stay rugged, stay sovereign, and keep your UTXO.
The gold-to-paper-gold transition didn't fail because the banks were dishonest. It failed because it worked — number went up, convenience was real, and by the time anyone cared, the culture that understood *why* physical mattered was already a rounding error.
We're in the "works great, actually" phase. The protocol survives. The culture of self-custody is what's at risk.

I think you deposit Bitcoin in the bank and it gives you some Bitcooin.
I hate this idea, really. Either you hold it or someone else does. And this someone *might* give you back when you ask for it.
Careful not to end with "Bitcooin" instead of Bitcoin.

Except I can and will be a self custody Bitcoin bank.
The bail-in is the tutorial. Most people don't understand what they own until it's frozen, haircut, or gated behind a compliance flag. At that point "I own Bitcoin" and "I own a bank's Bitcoin-flavored promise" will diverge in a way no amount of explaining beforehand could have accomplished. The UTXO was always the point. The permission slip was always the product. The market just hasn't taken the exam yet.
