@BtcCatalunya Yo añadiria lo que mi profesora de economia me decia mucho cuando iba al instituto: “No pongas todos los huevos en la misma cesta”. Si tienes 40 BTC no los pongas todos juntos, separalos para que solo se vea afectado un x %

How I'd Secure a Life Changing Amount of Bitcoin

If I were helping a friend secure a life changing amount of Bitcoin from scratch, this is the process I'd recommend:

1. Purchase two Bitcoin only hardware wallets from two different vendors and create a collaborative custody 2 of 3 multisig vault with @unchained , where you hold two keys and Unchained securely holds the third.

2. Generate each hardware wallet 24 word seed using a minimum of 100 dice rolls. Do not rely solely on the hardware wallet's random number generator.

3. Back up each seed on titanium and store every backup in separate secure geographic locations.

4. Download and save the Bitcoin config file immediately. Print multiple paper copies and store them in separate secure geographic locations. Unchained also retains a copy, but your recovery plan should never depend on a third party. This file contains the information required to reconstruct your multisig wallet, including the xpubs and derivation paths.

5. Import the Bitcoin config file into Sparrow Wallet.

6. Compare the receive addresses shown in Sparrow Wallet with those shown in Unchained and ensure they match exactly.

7. Send a small amount of bitcoin to your new multisig wallet.

8. Confirm the UTXO appears correctly in both Sparrow Wallet and Unchained.

9. Wipe both signing devices completely.

10. Recreate the watch only wallet in Sparrow Wallet using only the Bitcoin config file.

11. Restore both signing devices from their titanium seed backups.

12. Verify each restored signing device can successfully participate in signing for the reconstructed wallet using your normal workflow, whether USB, QR codes or microSD. Confirm the receive addresses still match those shown in Unchained and that the test UTXO is visible.

13. Spend the test bitcoin to a separate wallet you control and verify the transaction is successfully broadcast and confirmed.

14. Never use that original receive address again. Generate a fresh receive address for your long term bitcoin holdings and always use a fresh receive address for every future deposit.

15. Only after successfully completing every step above should you transfer a meaningful amount of bitcoin to the new receive address.

I hope someone finds this useful. This isn't the only way to self custody bitcoin. It's simply the process I'd be comfortable recommending to friends and family.

[Zynx @ZynxBTC]

I am getting a lot of questions about a Bitcoin multi-sig setup so I thought I'd create this quick guide.

This is now the gold standard for serious self custody.

Any single device can fail or have a flaw. Multi-sig removes the single point of failure.

1) The equipment:

Mix your hardware brands. A bug in one vendor's firmware cannot touch a setup where the other two keys come from different manufacturers.

-Trezor Safe 5 (wallet 1)
-Blockstream Jade (wallet 2)
-BitBox02 (wallet 3)
-Sparrow Wallet (desktop-only) as your coordinator

2) Generate your keys:

Set up all three devices completely independently. Secure the 12 or 24 word seed phrase for each. You now have three unrelated wallets.

3) Export the public keys:

Open Sparrow. Plug in each device and export its XPUB. XPUBs only read balances, they cannot move funds. This step is safe.

Make sure all three devices use the same script type, for example Native SegWit. Mixing address types across devices will cause errors in Sparrow.

4) Build the vault:

New Wallet, Multi-Signature 2-of-3. Import all three XPUBs. Sparrow merges them into a single vault.

Save and print the Wallet Configuration File. This is your blueprint and this is where people get caught out.

Two seeds spend your Bitcoin. Three XPUBs find it.

Bitcoin locks multi-sig funds to all three public keys simultaneously. Feed Sparrow only two XPUBs and it generates completely different addresses. Your balance shows zero. The coins are still there, you just cannot see them.

XPUBs cannot move your funds, but anyone holding them can see your entire balance and transaction history. Keep a copy of the blueprint wherever a seed lives, and store it with the same care.

5) Test it:

Send $5 to your new multi-sig address, then spend it back out. Sparrow will ask you to sign with any two devices.

If the spend works, your setup works. Do not skip this.

6) Separate your backups:

Never store them in the same place.

For example...

-Home: Seed 1 + blueprint
-Close relative's home: Seed 2 + blueprint
-Third location: Seed 3 + blueprint

You can also keep an extra copy of the blueprint on its own somewhere separate. It cannot spend anything by itself.

The absolute rule is that no single location should ever hold two seeds. Two seeds plus the blueprint is a spendable wallet and the blueprint is not secret enough to rely on as protection.

Why 2-of-3 works:

House burns down? Retrieve the other two seeds and recover everything.

One device compromised by a firmware flaw? Your Bitcoin is safe. They need two.

I have not covered passphrases to keep this simple.

I hope this helps. Happy to assist if anyone needs any support.

Para aquellos que quiere crear una multifirma 2-de-3 con múltiples hardware wallets de proveedores diferentes, les comparto este video del curso de la Bitbox02 Nova.

En este video (creado hace algunos meses), te explico que es una multifirma, como funciona y el paso a paso para que la configures con una @COLDCARDwallet Mk5, una @BitBoxSwiss O2 Nova y una @BlockstreamJade Plus, utilizando @SparrowWallet .

Compartánlo así más bitcoiners hacen un upgrade de seguridad.

Lo de COLDCARD es gordo.

Si te estás despertando ahora, actualízate y actua. Preparando algo para aclarar y ayudar al máximo

[Kevin Loaec 🧙‍♂️🐟 @KLoaec]

As people are still finding this 5h old post, here is what is happening:
- Coldcard MK3 random number generator is broken. Your funds are at IMMEDIATE RISK of being stolen
- MK4 and higher may be vulnerable to a more difficult attack, investigation ongoing. You are not at immediate risk, but may be in the long term.
- a multisig of MK3s is also AT IMMEDIATE RISK
- a weak passphrase or a few dice rolls on your MK3 are only buying you some time, and WILL GET BROKEN.

A strong passphrase (randomly generated and long) or a full entropy by dice rolls (90+ rolls) are SAFE.

What to do:
If you have an MK3 (or generated your seed on one), move your funds immediately. This is a race against the clock. Do not wait for tomorrow.

In any case, move to multisig in the near future, with multiple brands of signing devices. Consider using @lianabitcoin

Tengo un chalet en El encinar del Alberche, tenemos nuestro suministro propio de agua desde los años 60, punto limpio, basura, etc. Solo falta un cementerio.

@OscarBForestal @yyoquetedigo Tu exprésate como quieras, lo q nos faltaba... suficiente tenemos con la poca informacion real que llega como para encima atender a ofendidito que no quieren ver la realidad. Mucho animo! Yo tb soy de la zona, tenemos un chalet en el Encinar y no sabemos nada desde que se inicio.

@Julioencerce @pkas1111 Yo tengo un chalet en la zona, no puedo recoger una piña ni una puta rama para calentarme en invierno, estaria dispuesto a ello, asi que no me jodas… el problema no son los chalets.
