There are three reasons to keep your savings in a bank: 1. Investment opportunities. Banks offer relatively safe investment options, but their safety depends on a stable political system that prevents politicians from changing the laws to seize your savings. 2. Inflation protection. Banks may give you tools for offseting an artificially created inflation (money printing), which would otherwise be a hassle to manage on your own. 3. Physical security. Keeping your savings at home exposes you to the risk of theft or physical violence. The Western world has been operating under reason 2 for a long time. I think we're now transitioning to reason 3. #Bitcoin

Are you excited about the recent Bitcoin surge? Do you check the price before you even get out of bed? I vibe-coded an Android alarm clock that wakes you with happy music if BTC went up overnight, and sad music if it went down. Set it once, every day, or chosen weekdays. At alarm time it fetches BTC/USD, then plays Number Go Up or Number Go Down on the Android alarm stream. Press Stop and it reads the price.

I initially wanted to build the TimelockRecovery.com feature for Sparrow Wallet, one of the most popular wallets for advanced Bitcoin management, including multisig, air-gapped wallets, and more. But Sparrow is written in Java, and I've never worked on a large Java project, let alone one with a UI. So I implemented it in Python for Specter and Electrum instead. This week, I fed Grok and Fable the source code from Specter and Electrum and told them to replicate the mechanism in Java for Sparrow. A few prompts later, with some tiny improvements, and it works perfectly! 🤩 As a developer, it feels like knowing a few words of Latin and suddenly being able to speak any Latin-derived language. We live in amazing times!

The idea that multisig wallets are created by importing xpubs (Zpubs) to a hot online computer and building the wallet descriptor there - is absurd. That computer can manipulate the xpubs of some of the signers, add another xpub inside the QR code that doesn't appear in text form, change the number of required signers, etc. Most users won't notice the difference on their small hw wallet display, and won't verify a receive-address on all wallets (i.e. hacker can replace one of the xpubs with his own, and could fool you into sending funds to an address where they are a co-signer). The wallet descriptors should be generated on the hardware wallets themselves, with clear instructions how to verify them on all other hw wallets.
