Here's the passphrase setup I've used and recommended for years: I call it: Phrase-in-Phrase > Set up a hardware wallet with 24-word seed > Set up another wallet with new 24-word seed > Add decoy funds to both wallets > Use the second seed as passphrase added to the first one (first 4 letters of each word). Double-check passphrase entry. Store savings here. > Multiple backups of each seed > Set up notifications for both decoy wallets. > One seed compromised? Decoy funds move → you've still got time to move your funds safely > Sealed inheritance letter with restore instructions stored with lawyer, executor, or heir No need to store public keys or descriptors No third parties Works with most major wallets (Trezor limits passphrase to 50 chars) Multisig security. Singlesig simplicity

Don’t do this
Rolling a die 60 times takes 2 minutes. Converting it to a seed phrase takes 1 minute. Is your Bitcoin worth 3 minutes of your time?

This is how over-reaction look like, folks. What absolutely terrible advice - using custom, vibe-coded software on a standard computer to generate recovery seeds. This is a disaster in the making.

Bitcoiners favored recommending Coldcard for 2 reasons only: 1. They were being paid to shill it. 2. Because it was Bitcoin Only This is Bitcoin Only Fans mentality taking precedence over technical proficiency, accountability and security.

At @AnchorWatch we leverage this exact advanced bitcoin security @Ledger devices to be able to offer 1:1 insured custody against the loss of your bitcoin. I was one of the first beta testers of the miniscript firmware with @KLoaec of @Wizardsardine the creators of @lianabitcoin. I am so grateful of @salvatoshi for pioneering this within the bitcoin wallet ecosystem 🙏
After the recent Coldcard incident, I've seen a lot of people suddenly rushing into multisig. A word of caution. Multisig is not automatically the right answer. The UX has improved dramatically over the past few years, but building a robust multisig setup still takes careful planning. I regularly see people locking themselves into configurations that are painful, and sometimes impossible, to recover from safely. Adding keys buys you resilience against a single point of failure. It also adds complexity, and complexity is where people lose funds. Both of these are true at once. An alternative worth considering: Miniscript. Ledger has (one of) the most complete implementations of Bitcoin Miniscript, with clear signing on every spending path. You can express sophisticated policies, inheritance, 2-of-3 multisig, recovery keys with timelocks, and much more, while keeping the security of a hardware wallet and seeing exactly what you sign, every time. (More here ➤ ledger.com/blog/how-ledgers-… ) The other half of the puzzle is the frontend. Ledger Live doesn't ship a multisig option today, but good options exist. Liana (@lianabitcoin) for instance, does a good job of hiding the underlying complexity, making advanced policies accessible without forcing users to think in terms of scripts or descriptors. For developers, it gets more interesting. A few months ago I built a custom wallet UX around Miniscript. With Claude, I had a fully functional Bitcoin wallet supporting advanced spending policies in a few hours. I was comfortable testing it directly on mainnet, because every policy and every signature is displayed on the device itself. That is the whole point of clear signing: it is very hard to accidentally sign something different from what your application intends. What You See Is What You Sign. If you care about the future of trustless Bitcoin wallets, read @salvatoshi 's post on why Miniscript is such a powerful building block ➤ ledger.com/blog/towards-a-tr… And if you want the cryptographic version of multisig rather than the script version, Ledger devices are, to my knowledge, the only hardware wallets that support MuSig2 today. Several signers aggregate their keys into a single Schnorr key and produce a single signature, so on-chain it is indistinguishable from a normal spend. Smaller, more private, and still clear signed on the device ➤ ledger.com/blog-musig2-ledge… Multisig can absolutely be the right tool. So can Miniscript. Just choose it because your threat model demands it, not because a headline scared you into it. But, for most people, single-sig is still the right answer: a certified hardware wallet, built on a certified secure element, with real backup options and clear signing on every flow. Stay safe. Stay honest about your trust assumptions.

good randomness is better than multivendor multisig for the vast majority of people

"runs" These 4 characters are the only description of the 1534 lines of code that introduced the Coldcard entropy bug Imagine going in for open-heart surgery and the surgeon’s entire operating notes for the critical part simply say: “beats” That’s the level of care we’re dealing with here
exceptionally well written and breaks down just how sloppy coldcard code was well even for people who aren’t software developers. it appears they didn’t really understand the code that was calling their RNG, and when a logic error flagged that should have alerted them, they did the equivalent of hitting the snooze button they never ran this down. never interrogated what was happening, never made absolutely sure it was running as expected. on literally the most critical function in the entire product. after reading this, I would never touch a product of theirs again. totally unserious people.

Remember how bitcoin maxis used to shit on crypto wallets such as @Trezor, @Ledger, and @BitBoxSwiss ? They said supporting shitcoins increased their attack surface But as I see it, the popularity of crypto wallets makes them more secure, not less Why? Higher stakes, better funding, more scrutiny

Update: the App Review Board has confirmed that my Apple Developer account will not be terminated. Sparrow on macOS is safe. Thank you to everyone who shared and reached out in the past 24 hours - I'm grateful. And credit to @Apple for reviewing the appeal and reaching the right outcome. The deeper problem hasn't gone away: apps impersonating @SparrowWallet are still reaching users and putting their funds at risk. I'll keep working to protect people from those scams, and I hope to do so alongside @Apple. Thank you all.
My attempt to protect users from scam apps on the @AppStore has gotten my Apple Developer account flagged for termination - ironically, for "dishonest activity". Unless it's reversed by June 30, all new installs of Sparrow Wallet will fail, and development on macOS will end. The context: since 2023, more than a dozen fake "Sparrow" apps have appeared on the App Store, as recently as April this year. Users have contacted me after losing their savings, in some cases their life savings, to these impersonators. I'm the developer of the real Sparrow Wallet, a desktop app, and I hold the registered US trademarks for the name and logo. I have publicly warned @Apple and the community about these fake apps from early 2024, but they keep appearing. The app @Apple flagged was a placeholder that was never published. Its only purpose was to warn users that Sparrow is desktop-only and that other "Sparrow" apps aren't mine. This approach may have been misguided, but there was nothing dishonest about it. I'm confident this is an automated misclassification that Apple would reverse on review - but I may be terminated before a human ever looks at my appeal. The cost would fall on @Apple's own users: blocked installs and no updates for a tool people rely on, which opens the door for more fakes. If you value Sparrow, a repost would help. @AppleSupport

The four-year cycle has been Bitcoin's most reliable pattern. So reliable that many investors are still waiting for $30K Bitcoin But this cycle isn't like any other... 2025 finished negative. The first time ever for a post-halving year. And in February, the largest realized loss event in Bitcoin's history played out At a 52% drawdown. Not even close to the usual 70-80% The floor signals fired anyway. The bottom is already in. Full breakdown in the video below👇

As a litigator handling bitcoin and crypto cases, I’ve seen firsthand the messy collision between Bitcoin and the law. Assets seized and frozen on-chain. Grey areas where the law breaks down. So I wrote a Bitcoin thriller. A lawyer gets handed the keys to billions in Bitcoin. His client vanishes. The cartel wants it. The FBI wants it. The legal system won't save him. UNCONFISCATABLE is up for pre-order on AMZN below👇. I’ve been working on this for over two years and pre-orders genuinely help boost launch day rankings and get the book in front of new readers. FIRST 100 paperback orders get a special gift. DM me proof of purchase.
