A note to #nostr there are free spreadsheets on this page for you to explore the mechanisms of #bitcoin, including the sha256 algo, the actual ECDSA secp256k1 calculation in both decimal and in binary, the RIPEMD160 algo, 12th and 24th word calculations, an in-spreadsheet bitcoin miner, even nsec generators for nostr! A quirky favourite is the in-spreadsheet QR code generator, great for jumping information from the monitor to your phone! Got one in there for #seedsigner's compactSeedQR, as well. All of these are designed to operate on your machine, no macros, no array formulas, no add-ins, no sending data to the internet, that is, fully transparent to you, the user. Good for learning, playing or serious checking and generating. Enjoy and let us know if you have questions.🤔😉

With fiat paper, people will acquire the note for its burn-energy value, establishing a floor to its value. With CBDC, the floor value is removed. As if you needed another reason to stay away from CBDC. #fiat #cbdc #bitcoin

Does anyone else notice that Barrons.com articles are either slightly or fully pessimistic on #bitcoin, and when they are reporting NgU it is “bitcoin and xrp”? Almost like someone there is being paid to shill xrp…

Arizona Gov. Katie Hobbs’ veto of bitcoin bill (Senate Bill 1025) on May 2nd, 2025 cost Arizonans $325 million, as of today: $324,742,268 foregone. $45 for every man, woman and child today. But who’s counting? ($70bn (round numbers) x 10% allowed to be invested x (($101,500 BTC price today - $97,000 BTC price at veto) / $97,000)) #arizona #bitcoin #katiehobbs

Why are so many people celebrating #revolut and #strike and #cashapp and #fold and ____’s ability to use #bitcoin rails for fiat payments when you have to fully KYC yourself and give up control in order to use their platforms? It’s almost like these people forget bitcoin is there to help your independence and sovereignty, not to add to your corporate shackles.
