Great video. Going to use this when setting up my coldcard. FYI - If anyone is wondering about the screen flickering on the coldcard, it's to do with the frame rate the video was shot at not the screen itself.

👍Best review. Unique wallet. A study in productive paranoia. Not for the weak minded. Lots of details. Thank you for taking us through the looking glass.

Es el mejor tutorial explicativo que me he podido encontrar en internet. Me ha costado entender algunas cosas porque no hablo muy bien el idioma pero, lo cierto es que en español hay poco contenido sobre esta hardwallet. Aún así, lo has puesto muy fácil y muy claro, te lo agradezco. Espero que siga creciendo tu canal porque aporta mucho valor, yo me suscribo. Un saludo.

[@user-hs6wt2fk9e]

Nice one. Coldcard remains the most reliable hardware wallet in the market IMO. Ledger, Trezor, Passports, Bitbox, meh. Gimme a Coldcard. Mk3 or Mk4. If you know enough about who is making them, how they're made and how you can verify... good way to go. Don't trust tho, verify.

@1:14:05 what gets actually saved to the SD-card @ setting up BIP-85 derived secret? The plain-text 12-word seed unencrypted? And what is the use case of this saved file? Where do I have to store it (in comparison the backup of Coldcard is in an encrypted file...)

[@carlpoppa1788]

Underrated and subscribed. I was wondering when you are carrying a partial transaction from your PC to your wallet for signing, is there a way a malware can be carried into you wallet that steals your private keys? Great video btw. It's people like you, that are educating others on the strengths of Bitcoin and how to utilize it, that make the difference. 👍

[@BTCSessions]

Thanks for the comment, and great question! The keys are segregated on the device to prevent this. My understanding is that the SD card doesn't have access to the keys, only the finished signed transaction. I'll perhaps defer to Rodolfo at coinkite for clarification on this though.

[@MrFooChops]

@@BTCSessions Any update on this critical point?

[@712Jefferson]

This was a fantastic learning resource. Thank you so much!

[@Brendjord]

I see the coldcard can come bundled with more than one SD card. Are these spare cards in case one goes bust, ore do more than one SD card serve a purpose?

[@bilalabesat]

This is the best review i ever seen for a hw wallet. I hope you will make a similar one for the new Q1.

[@pachmann4869]

encrypting a backup of the seed phrase onto an extra sd card requires knowing another multi word password.. ...so you're hiding your private key with another long password. can someone please explain why to do this? it sorta makes sense, but i can't explain why

[@fr2738]

Does anyone know what this part at 23:20 is? I am trying to setup XPUB for pocketbitcoin recurring purchases, and in their tutorial they say you should use account number 1 for pocket when exportting your wallet with generic json. I don't understand why that is? Are account numbers just other bitcoin public addresses or?

[@BTCSessions]

My understanding is that it's the "pathway" used to generate addresses. Your hardware can generate a massive number of bitcoin addresses, and you need to decide which ones your wallet starts from. Changing the account number from blank (technically account 0) will change your starting point. When pocketbitcoin says account 1, they likely mean just the default pathway.

[@live4action]

[@antoniocouto7092]

Thanks for the tutorial. Do you know if in the coldcard is possible the see the seed phrase in case you lost the paper you noted to? The Trezor and others is not possible to do that. regards.

[@carlwatts1230]

Relating to the part where you created a backup and then restored the wallet using that backup: didn't you say it was an encrypted backup? I didn't see you enter a passphrase or decrypt anything. Did i miss anything? What could a person who found the file or the wordlist do with it? Or is it that the backup file is an encrypted file and the wordlist is the key to decrypt it? Probably that now that I write and think about it. I'll leave the comment in case it wasn't clear to anyone else.

[@BTCSessions]

Haha yes you indeed figured it out mid-comment.

Assuming you have a bricked Coldcard. Once you import your seed phrase and as long as you have the correct identity, can you use the existing Sparrow wallet(s) that you have created? Coinkite tell me I need to know the path???

Appreciate the detailed breakdown! I need some advice: I have a SafePal wallet with USDT, and I have the seed phrase. (alarm fetch churn bridge exercise tape speak race clerk couch crater letter). Could you explain how to move them to Binance?

[@postmanprints]

Thanks for the video. I am trying to sign a transaction, and I see a “change back” address. The amount is drastically less than the difference between the amount I’m sending and the amount I should have left over. Can you explain what the change back address and amount means?

wish you could have explained the different options for the decoy wallet. Would have been nice to hear more about the "brick" that you keep referring to. What does this mean>? What is the point of having a Brick Cold Card, as you nor anyone can access it? You didn't explain that part but you went on and on about the very obvious implications of a $5 wrench attack...

[@primal9958]

Is there any reason at all that it wouldn't start up after you've plugged into an adapter (lights are on both adapter and cable connection)? Is there something I'm missing here? Or have I received a dud?

[@rideak56]

When you first received BTC into the ColdCard wallet I did not see where you saved the PSBT to your SD card and then loaded the SD card into the Coldcard for signing? I have been trying to do this with my Sparrow Wallet (on a MacBook as well) and a ColdCard (MK4 with the latest Firmware) and I keep getting the error code: "Failure. My XFP not Involved". I Checked my Coldcard Master Fingerprint and my Sparrow wallet for the cold card and they have the same fingerprint...Any thoughts?

[@billfrenger8955]

Thank you Ben, what wallet would you recommend for the phone. Would that work on a De-Googled Pixel phone? Regarding using the Coldcard with Sparrow are there any special provisions that need to be made for PC's that are running Linux Ubuntu 22.04?

[@gumnut-gt6io]

Thank you for this comprehensive video. Is there any difference between cloning the cold card and simply putting in your 24-word seed into the new cold card?

[@BTCSessions]

No worries! So cloning will basically copy all your settings/preferences PLUS any items you have in a new feature (which I made a video on) called seed vault. Importing the seed is fine as well, this just streamlines the process and grabs any additional info you've imported.

[@sumitchowdhary]

watching your videos form last year ,Thank you for giving so much valuable information . I have a silly question in my mind , if i create sparrow multisig wallet , and for some reason government take down sparrow and electrum , then how can i restore my multisig ?

[@danobrien3760]

I am wondering about the Sparrow steps taken before the initial opening of the Sparrow app in this video. I see at the bottom of your app screen there is a slider that is blue, and before that it can be yellow. How do you go about learning that part?

[@phil_lip1164]

Yeh, I didn’t see that either and couldn’t understand why my btc was not showing up in the wallet. Then thought I would just hit the toggle button which was off when the app was downloaded and voila, the btc had arrived which was a huge relief

On the passphrase section when it gives you the option to save to SD card, that is to save the actual passphrase. It's not to save the xpub for exporting to another wallet.

[@copycatt2579]

If you save the passphrase does that mean you don’t have to type it in when using your pin? It will auto add the passphrase to switch to the correct wallet?

Really appreciate the helpful and informative content you put out. I am considering a Mk4 but have a new Keystone 3 Pro which I was planning to use for BTC alone to HODL only. When Keystone release their dedicated BTC firmware next year, will the Keystone be comparable to a Mk4 in terms of security? I will use a Tangem most likely for daily transactions of I do any. Many thanks 'eh :)

Hey BTC Sess, my Mac won't open the dfu file in order to upgrade firmware. Any suggestions. it just opens a blank document and if I search for a file too open it nothing happens.

[@josephjimenez3291]

I have my mk4 coldcard with wasabi as my desktop wallet but I’ve been hearing disappointing news about wasabi regarding privacy. If I want to switch over to sparrow wallet, do I simply initiate an import to sparrow wallet as was done in the video? From there would I need to do anything else with wasabi in order to access my stack?

[@BTCSessions]

You're exactly right - simply import and you're set! Regarding Wasabi, I was also disappointed. However, it only pertains to the coinjoin function of the wallet - so if you opt to use it as a basic desktop wallet it will still function with the same basic privacy. That said - Sparrow is awesome.

[@se6586]

If you use wasabi are you required to use a 25th word with the cc? Or that’s only required in wasab for a desktop wallet?

[@BTCSessions]

The password with wasabi is just to unlock the desktop software itself if I'm not mistaken. It has no bearing on the actual seed phrase of your Coldcard. It's basically a mechanism to prevent someone from auditing your balance if they get access to your computer.

[@se6586]

@@BTCSessions thank you for the reply. I have gone through your tutorials and checked out everything cold card has put out and I didn’t know if it encrypted via the 25th word which would make it incompatible with 24 word seed wallets, which is my concern. I haven’t been able to find a solid answer

[@BTCSessions]

@@se6586 so with Coldcard, you put your 25th word into the hardware itself, then you can access it from any 3rd party wallet software. I would not add anything else outside of this, as it can complicate things and possibly result in user error.

Currently you can use Blue Wallet on mobile with Coldcard. It may be a little clunky saving files and porting them over with SD card to a mobile device, but it sounds like Blue will be the first to incorporate NFC soon - so that will make CC/Blue incredibly easy when it drops.

I had previously purchased a Trezor Model T, via the referral link, after watching your video's a little over a year ago. However, I don't have a backup hardware wallet, so I was looking to purchase one. After watching your Top 6 Bitcoin Hardware wallets of 2022, I narrowed it down to the Coldcard or the Keystone. After watching both of your detailed usage videos on each of the two, I am leaning more toward purchasing the Coldcard Wallet (via your referral link). Then after copying the wallets created on the Trezor to the Coldcard, I plan to wipe the Trezor and have it as the backup as it is less secure than the Trezor due to the Coldcard being air-gapped. Thanks once again, Ben!!! One question: Would you recommend using the Micro SD over the Virtual Disk with the Coldcard?

[@JamesClifford1]

Awesome Video Ben! Thank you! I received my Cold Card and walked my way through with your help. I appreciated the discount that I received by using your link when purchasing it. I chose to use unsigned transactions with the micro USB as it is the most secure being totally air-gapped. When Sparrow Wallet supports NFC I will switch to NFC.
