wow 😳... thank you!
nice bro keep it up
BTC sessions should send you some sats for this
Amazing tutorial.Thank you for all the hard work you do, that wasn't easy to shoot and time intensive but we all appreciate it. Thank you so much.
hear hear!
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.
100 - thanks for this comment! The flicker is unfortunate but definitely not true to real life
👍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. This must be the most secure BTC wallet in existence. There is relatively little information about this wallet when searching UA-cam. You did a valuable video. Thank you.
Info starts at 5 minutes
I had been stressing about how to restore. It's so much easier than I thought. Thank you so much. This was fantastic and easy to follow.
Love your tutorials!🧡🙌🏼🚀 please start taping in 1080p or 4k if possible. Thanks so much for all the hard work! 🧡
Fantastic tutorial! Very timely as mine arrived not too long ago! Been a long time watcher, keep up the great content!
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.
I am currently waiting on the Mk4. First hardware wallet I've ever bought. Ngl I was scared because I do not consider myself a technical guy. This video is a great tutorial for plebs like myself.
TY for your work Ben, I tipped some sats over strike.
Man, this was the best tutorial I've ever watched. Thank you so much.
Most complete ColdCard tutorial out there
Saving up to buy one.
Awesome review - will be referencing this in the future.
Thanks, man
This was a fantastic learning resource. Thank you so much!
Your tutorials are outstanding. Your generosity is one for the record books. Your dedication shows through your obvious talent. Thank you sir for all that you do.
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.
We appreciate your extraordinary efforts sir. Great video.
This is the best review i ever seen for a hw wallet. I hope you will make a similar one for the new Q1.
Great walk-through. Thanks for the great detail!
Really appreciate bro, thanks for spending that time for the whole thing!
Outstanding Ben, as usual - thank you so much!!
Best btc Channel!
amazing tutorial. thank you so much!
Wow - what an amazing podcast. Thank you!
Very thorough! Great job!
Really appreciate your tutorials, thank you very much
Very descriptive and usefull tutorial. Thx for your effort brother, greetings from Turkiye
This was massively helpful!
Thanks for your time, and expertise!!!
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. 👍
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.
@@BTCSessions Any update on this critical point?
Strike Tip sent your way Ben. Thanks for another great tutorial
One more priceless video. Thank you so much!
Best video! Thank you.
Thanks for the video, very helpful
Super helpful, thank you boss!!
Made in Canada!
Thank you this tutorial help me a lot ❤❤❤❤
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 :)
Thank you sir 🙏🙏.
Great video. And you accent is awesome. Unfortunately we dont have good tutorials like this one in portuguese.
make one? Brazil and Angola need your help
Thanks Ben
Thanks!
Fantastic tutorial ben! Do you not recommend verifying coldcard firmware
FABULOUS video! May I ask that you do a "How to buy bitcoin video using ColdCard and Bitwell Bitcoin"? I see Bull Bitcoin does not have the etransfer feature working on their site right now. Might be another option for Canadians. :-)
@BTCSessions - noticed when using air gapp to create a Sparrow Wallet with ColdCard your exported the generic JSON however, now ColdCard has a Sparrow Wallet export...do you now export that instead of the generic JSON from ColdCard? Thanks
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?
Nice Tutorial !!
Had a question - does it work with Exodus wallet?
Appreciate inputs. Thanks.
If the MicroSD card that the wallet was exported onto breaks, what would happen? Would you have to re-export another wallet with a new MicroSD card?
Yes.
Hi Ben, do you suggest Wasabi, Sparrow or Electrum to use with coldcard? I used to use wasabi a few years back. thanks in advance brother.
How do you do a air gapped transfer with the new version of Wasabi? I can't find it.
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?
Great Video. Question - I was going to buy this wallet and some accessories but there's only an option to pay with a Gift Card or with BTC. Where can I buy these items using dollars?
Ledger lead me here. Thanks to Ledger, I'm now looking for alternative storage where I have my keys.
Complete newb question... migrating here from ledger, so ty for this video. Can I use a USB C cable plugged in to mains rather than battery?
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 ?
@50:58 what exactly do the bars on the right side of the CC's display mean? Enthropy/ bit weight? ...and how to interpret them?
This is awsome
Thx
Can you use a USB-c card reader instead of inserting the Micro SD Card directly?
Great video thanks. Question,: I developed a habit to the LIVE mobile interface where I could view my bitcoin. Is there any mobile interface I can use with Sparrow to see my BTC on mobile? Thanks!
Hi Ben can you use a regular wall usb c charger yo turn on CC?
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
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?
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...
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?
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?
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.
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?
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.
It would be great if you could do a ledger wallet to coldcard backup
What do you think about Tangem wallet? About to buy Coldcard but saw some people hyping this one?
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.
Have you tested mk4 NFC transactions?
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.
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?
@@copycatt2579 yes, but you have to insert the SD card
I was confused about the duress features. If the seed and device are erased, then how would I recover?
Does this coldcard only work for BTC or can it be used with alt coins? Thanks
Is seed XOR basically the coldcard's version of shamir?
In my coldcard I have one option more than you and when I press ( export Wallet I have an option as sparrow wallet??
I try to save a transaction for sending on to the micro SD and get an error message that says Error saving PSBT
Brilliant, thank you very much. “Digits of words” are called letters. 😂
Anyone else receive a coldcard that says “Bag Me Now” at first power on? I assume it means it wasn’t setup properly prior to shipping and I’ll need a replacement. Hopefully product support is good.
Sparrow doesn't find my mk3 when I scan for connected hardware wallets, is this a known problem?
I am using an old MacBook which might die soon. If my computer fries, how do I back up my cold card so I can use sparrow on my new computer?
export json file include public key only?
5 star explination! Can anyone send me where i can find read the terms of sale and use- full document? Thanks
I consider myself pretty tech savy! But even for me this looks very complicated to use!!
There is absolutely NO WAY the average person will be comfortable using this device!!
Great
nice
Have you heard anything about Tangem wallet? it's cold hardware wallet that looks like a regular credit card and the keys are stored in it. Would love to see a review from you on the wallet
I love it personally but I don’t understand it all including possible security vulnerabilities. Seems secure though and it’s super user friendly
Can we use a windows computer to do this
¿Is there any way to verify that the manufacturer of this device actually delivers on what they promise and the cold card is actually safe?
do you need the SD card?
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.
Haha yes you indeed figured it out mid-comment.
fucking amazing man.
Well done.
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?
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
Had to watch tons more videos, but now I got it. Since your new and learning, glad to have you on board !@@phil_lip1164
when 4k quality?
Could be nice a tutorial with bitcoin core
Thanks for showing the neede Los complexity and horrible use ability of this piece of hardware.
ColdCard vs Keystone?
funny thing is considering air gapped a device that use to plug an sd card into a connected device... you might rethink of security here...
Can you do a video like this for the keystone pro!?!
Here ya go! ua-cam.com/video/4KDQqj02KK0/v-deo.html
