How to Use a Coldcard Hard Wallet for Bitcoin Self Custody with BTC Sessions

[@jybevox]

MOST IMPORTANT STEP After generating your seed, please, don't forget to RESET your ColdCard device, and re-import you mnemonic seed (aka your 12 words) on it. That way, you'll be CERTAIN that you're able to restore your backup in the future if needed. This is THE MOST IMPORTANT STEP for your self-confidence using a cold wallet. You can transfer a few bucks on the wallet and reset again to be 100% sure. And don't forget to be proud of yourself becoming your own bank :)

[@asyxreds]

@@onpoint77408 Second option. I meant: "reset your device and re-enter the 24 words to be sure your backup is solid". (I answer with another account here). Also, remember that 12 words is enough (it's counterintuitive, because 24 words is NOT more secure, and don't bring any advantage over 12 words, except a stronger checksum). Google search "Make 12 Words the Standard" for more info.

[@didactica9326]

Do you mean reset before sending all your Bitcoin? Doing a small send then reset? And possibly a second time before your whole bag- is this accurate?

[@asyxreds]

@@didactica9326 Yes. The more you check today that your mnemonic phrase is working, the less you'll have to worry about it in the future. I reset it every 6 months, and my confidence in my backup is rock-solid. People who never even checked their backup once are now paralyzed by the idea that: "What is I'm not able to reset my ColdCard? I'm too scared to touch anything anymore". Help your future self by giving him today the tools he will need to feel confident tomorrow.

[@didactica9326]

@@asyxredsk thanks. And the reset is only necessary when you accidentally lose your PIN code correct?

[@asyxreds]

​@@onpoint77408 You don't need to use a second device. Using the same device to reset is fine (if you can test your seed on another device, it's great, but not necessary at all). Maybe you should also consider learning what's a "Master key fingerprint" is. When you enter your 12-or-24-word seeds, your ColdCard generate automatically a "Master key fingerprint" or simply "fingerprint" (same 12-or-24-words always generate the same "fingerprint"). After reseting your device, you should simply check that your "fingerprint" is the same as the one generated when you've set your device for the first time.

Thanks so much, Natalie and Ben! I was looking forward to this collaboration. High marks! No disappointment. I might need a "orange calculator". 😊

[@klunnikov]

Recently bought some recommended stocks and now they are just penny stocks. There seems to be more negative portfolios in the last 3rd half of 2023 and first half of this year with markets tumbling, soaring inflation, and banks going out of business. My concern is how can the rapid interest-rate hike be of favor to a value investor, or is it better avoiding stocks for a while?

[@fedorinovsubdivision]

The truth is that this is really not as difficult as many people presume it to be. It requires a certain level of diligence, no doubt, which is something ordinary investors lack, and so a financial advisor often comes in very handy. My friend just pulled in more than $84k last month alone from his investment with his advisor. That is how people are able to make such huge profits in the market.

[@nonshatter7]

This is a very informative video Natalie and I especially like your frequent questions at various stages - such as at 48:46 where you ask if Coldcard can access your seed phrase when connected. As for Ben, he is an excellent and diligent explainer of these things. One of the best in the business. On your channel, I have seen one more Coldcard Tutorial with Ben; I look forward to watching this later. Thanks.

thank you Natalie

[@hanionline563]

you need to memorize your seed phrase try to choose 12 instead of 24 you can regenerate the seed multiple times till you get words that are easy to memorize you can add a passphrase for more security

[@DonnaAnna-k1y]

Great show. Thanks for your generosity in doing this.

[@randomscandinavianguy4165]

I only watched maybe 10 min total of bits and pieces of the video, so maybe not fair to comment, nevertheless I'll give a few general comments to some remarks that were made: 1) It was said that air gapping is safer. This is not necessarily true. It is easy to perceive it as safer when there is no physical connection, but the thing is, there is still communication. Whether it is via QR-code or SD card, that is just a communication channel. No communication channel can prevent the transmission of tampered data (e.g., PSBTs or firmware). For example, withg regards to transferring data via SD cards, there could be attacks on your PC that reads and alters PSBTs. It is always up to the HW wallet to sanitize and show the data it receives. Also, remember, an SD card has a small computer inside which runs firmware. This is also a potential attack vector. 2) It was said that 24-word mnemonic are marginally safer than 12. It would say, not even that. In the end, regardless of the length of the seed (the actual, random number) it all gets hashed down to 256 bits. Because if the way ECDSA works, this gives roughly 128 bits security in either case. The seed itself is much stronger with a 24-word mnemonic, but it doesn't matter, because an attacker does not need to find it. They can just find the private key instead (its length being independent of the number of words used). 3) It was said that open-source code is safer than closed source (we are not talking about the secure element here of course). The idea here is that it is harder for the code to contain backdoors when there are supposedly many eyes on it. This is quite likely correct, but the problem here is that it is next to impossible to be sure that a specific firmware is running on your HW wallet. There is no way to ensure the chip isn't running some malicious code. Even if you have verified signatures for the firmware download.

[@farah-5538]

Also, what's the point of a cold wallet if you have to use another online wallet to use it ? (Total newb here, nonetheless)

[@thekaku1108]

Your video is extremely helpful! Thank you.

[@BBKeys1947]

Can you please do a video on how to do this with the ultra safe 'air gap' method. I don't want my wallet ever connected to the computer. I bought this card on your recommendation but their website videos and instructions are Not good.

[@Nonduality]

So the Coldcard hard wallet isn't a wallet but Sparrow is a wallet, right? I have another wallet I bought and can't figure it out no matter how many tutorials I watch. It's confusing for some of us old folks plus we gotta secure the seed phrase. So I'm doing the old person thing, investing diversely in GBTC, BTCX, MSTR, BitBuy exchange, COIN, and upcoming ETFs. Lyn Alden recommends some of those vehicles in her portfolios though it's clear she personally uses a cold wallet.

[@leoram6820]

great video Thank you

[@joebrusca4647]

Very helpful video. Got stuck at Sparrow scan. Getting no hardware wallet found. Anyone know why that would be if I'm connected to the PC and coldcard is in Ready to to sigh mode?

[@truestory923]

i had the same issue. I think it is because you didn't export your cold card to your computer properly. You have to use the sD card and an adaptor. Total pain imho. Also, it might be because your firmware isn't the latest, just a guess. I just got my CC in Oct 2023, and it was running firmware from June 2022. Pretty shitty of Coin Kite not to update their models with the latest firmware, but whatever. It seems that Coin kite is ruling the space and knows it. Customer service feels like practically non-existent. And what kind of company relies on KZbinrs to do tutorials, without doing their own? Ya, probably many, but that doesn't mean it's cool

[@bitcoinenergy1]

[@BitcoinAndChess]

This is a GREAT video tutorial and badly needed, but it does bring up some UX problems that NVK needs to be aware of. He needs to make the buttons far more intuitive. For example, the mistake Natalie made when she hit the check mark instead of the arrow button, which also is a number... it's too confusing for a beginner and scares them off.

[@d-boy1644]

even if you roll a dice , how can you verify trust that it’s still not a known seed from the manufacturer?

[@andrewriley2903]

Nat: What the deal with the micro SD? Do I need to buy those if I’m connecting my ColdCard via usb to computer?

Went to order a Coldcard from the manufacturer, Coinkite. Felt uncomfortable checking the box during checkout that states, “Coinkite is not responsible for damage if customs unseals your package”. Should I be concerned with making this purchase of the Coldcard? TIA
