Over the next few weeks, my “Bitcoin beginner” friend/colleague will move a decent amount of coin from an exchange to self-custody. I’m thinking we’ll start with Sparrow Wallet, to learn about key restoration and UTXOs (or is BlueWallet better for this?) and then to a HWW from there.

My question: should I make sure she installs a VPN on the computer first? Personally, I never do a Bitcoin transaction without a VPN enabled, but I don’t want to overwhelm a newbie with a digital privacy sermon, at the same time as our welcome-to-Bitcoin session.

Did anyone use the heat transfer of a frying pan to transmit a transaction yet?

Would be a nice weekend project: create an air-gapped transaction, build a little device that heats up a frying pan on one end, and once it hits a certain temperature threshold (measured at the other end) you book it as a binary ONE, and if it doesn't hit the threshold in a certain timeframe you book it as a binary ZERO.

The frying pan would literally act as a transmission device, and once the binary string is transmitted through the pan, you broadcast it to the network by whatever means. Bonus points if you broadcast via ham radio, just for the heck of it. And also because you could give it a nice name like "Ham in a Pan" 🥓🍳
