An interesting conversation is around the costs of setting up a secure (possibly airgapped) cold storage. People usually bring up the do-it-yourself Seedsigner (<$50) and Blockstream's Jade ($80 plus shipping). The conversation often includes usability (tiny screens and few buttons for both) and tinfoil hat aspects of security. What people don't usually mention is is the Coinkite Tapsigner ($20 plus shipping), probably because it's not a device per se, but an NFC card that signs transactions...

Merry Christmas everyone! A few days ago this tragic post was made to Xwitter: These posts come up from time to time and they're always heart breaking. Sometimes, it's a rugpull of some centralized service that gets hacked or runs away with user funds. Sometimes it's self custody gone wrong. Often, it shakes the foundations of people in the space who are new, not 100% confident in their wallet setup, or aren't comfortable with the growth in the value of their Bitcoin. This leads to controve...

My Values For a system like Bitcoin, I value...
