“Privacy is for criminals” is a psyop
Privacy is the best first line of defense you can have to protect yourself from criminals.
An exposed target is an easy target.
Politicians just want to get rid of privacy so they can rob you themselves.

The money in your bank account isn’t truly yours. The cash you physically hold isn’t truly yours either.
The Bitcoin you have on an exchange or an ETF isn’t truly yours. But the Bitcoin you hold yourself is your money.

The experience of Bitcoin self custody today looks nothing like what it was 10 years ago.
And it will look nothing like what it is today in 10 years.
We’re living in exciting times!

2025-01-11 23:27:49 UTC

Protecting your Bitcoin has no absolute solutions, it’s always a scale between simplicity and security and different solutions meet different needs on that scale.
Find the right one that works for you, and slowly move up the scale towards higher security.

I was referring more to small differences in technical standards especially PSBT and descriptors https://x.com/_benkaufman/status/1877743413606437283?s=46&t=gDN80H7X8cKaLPv_m770rg

Technical standards in Bitcoin are just so broken
We start off with a great well specified standard, then everyone has to make a tiny little tweak which just break compatibility with everyone else

The biggest challenge of getting people to self custody is not in the user experience, the tech, or the quality of wallets.
The biggest challenge is making people take responsibility for themselves instead of looking to shift it to a trusted 3rd party.

Politics shouldn’t be such an important part of daily life.
People shouldn’t be asking if the government should do this or that, they should ask why the hell is the government getting involved in the first place.

2024-05-09 03:50:09 UTC

No presidential candidate truly supports #Bitcoin , and even if one does, he won’t do or change anything favorably. At most he won’t worsen things too much.

2024-05-08 21:10:54 UTC

The goal of the government is not to kill #Bitcoin
It is to hollow it from any of its freedom, privacy, and censorship resistance properties and leave it as “rare digital tokens”
