[@jeffmcdonnell3300]

Thanks!

[@kallipto]

I just discovered your channel as I began a long journey of looking for a better hardware wallet. All indications point to the Coldcard Q as one of my best options. Your video and entire channel are incredible resources. The Bitcoin community thanks you for your hard work! :)

[@lonewolf1960]

Thought I would be able to pay with BTC that option didn't pop up for me, No problem, Thanks Ben !

[@video2350]

Great Video! Thanks for doing such a detailed tutorial on the Q.

[@dogismycoolpilot9662]

I can get the QR codes to work fine on a single sig wallet but on Multisig through sparrow it does not want to read the QR code generated by the coldcard. Curious if you could comment or possibly show a tutorial in another video for multisig. So far love the Q for the reasons you mentioned. It is just fast and easy to use compared with an MK4. The price difference isn't outrageous either.

[@jybevox]

What for having 2 SD cards entry? Why is the second one useful for?

[@jybevox]

Looking forward so much to see this video :)

[@stephengauntlett2603]

FYI you mention the microSD card to be no larger then 64gb but the website states 32gb. I tried the 64gb SD card and it is not recognized so I assume it needs to be 32gb max.

[@yasserkishawi]

Format it to be FAT32 it will work with you

[@GoldCross50_200]

Well done, you have a natural talent, good luck.

[@VamosViverFora]

Ben, you’re the best!

[@RedBeardOps]

I'm a huge fan of ColdCard wallets... that being said... if you had to pic a second best Bitcoin only company for hardware wallets who would it be?

[@Tinvested]

Do you prefer one over the other? Is it safe to use the Q for Nunchuck and Sparrow and have bitcoin in each wallet?

[@GarretHecker]

hi thanks for the videos, if doing this today december 2024 is there still a need to update the firmware with an SD card?

[@marcoshernandez745]

Thanks for this! I just ordered my cold card Q, I plan on using it air gapped with Nunchuk wallet 😀

[@nonshatter7]

Excellent explanations to your tutorial as usual.

[@Rusty-METAL-J]

I LOVE APPLE MacIntosh O/S. When I was in High School we had LC IIIs and we had O/S 5.¹ and 6.¹.

[@brb8829]

Is it possible (or even preferable) to send Bitcoin directly from an exchange to a Coldcard if the goal is simply to hold for the long-term? Do we need Sparrow or another type of intermediary wallet for that?

[@karolnagelbtc]

Bitcoin is on a blockchain, not on an exchange nor Coldcard.

[@stevejacobson7431]

Is a SeedSigner nearly as functional as ColdCard? I sure like the price of seedsigner as I have RaspPis laying around.

[@John-lz3hf]

One function I notice missing is SeedXOR. I'm sure there's others, but that's all I notice for my daily uses. There is code pending to add SeedXOR, and anyone can fork it and start using it now.

[@paulvincent1494]

Am I correct in assuming that if you already have an NFC key setup that you cannot also set up a QR key/wallet

[@toropocho]

This is an important question. Has anyone set up both methods?

[@recongraves]

​@@toropochostill looking

[@EE-gy1kf]

Hi. Is it possible to create a hidden wallet with the Q? That is, a wallet that has a passphrase on top of the 12 seed words?

[@hectormunoz4812]

Is there a way to set up the Q as a stateless device? I would like to skip creating a PIN number. In my blockstream jade I skipped PIN number and rely on scanning the QR code of my 12 word seed everytime I turn on the device.

[@trufiberusa7725]

coldcard q doesn't load black screen. Just bought it yesterday and all set up. Today I turned the Q on. The green light is on but nothing load up. Can someone help?

[@KyleLackinger]

21:00 does adding dice rolls add entropy or are you bypassing the onboard RNG and using just the dice if you press 4? How many additional rolls do you recommend? Nice video so far!

[@daanl8993]

Remind me!

[@recongraves]

Anything less than 100 dice roll is completely hackable

[@glauciahelena791]

Hi Ben, is it possible to use only one cold card Q on multisig, for multiple seeds, or is it not possible?

[@houdeshulmc]

I am unable to sign using the Qr code on my Coldcard Q. My fairly new Macbook Air Webcam was not able to pick it up.. This seems to be a common problem others are running in to. Any easy fixes?

[@nielsmoller2719]

how do I export a passphrase protected wallet from CC Q to Sparrow?

[@AshEllieRose]

Beautiful!! 😍

[@gh4534]

What accessories do you highly recommend to order with the Q model? I.e. power cable (or does it come with one)?

[@BTCSessions]

The only thing I think is really necessary is a microSD card for firmware upgrades. This means you'll also want a dongle that allows you to plug the SD card into your computer. If you're going to plug in the device directly then you can get a USB-C cable, but make sure it's one that actually transmits data (coinkite does not sell these). Other than that, just make sure you have some AAA batteries kicking around!

[@gh4534]

Very informative as always. Another question. One needs to get a wallet to work with Q. Q cannot function without a mobile or pc wallet?

[@recongraves]

​@@gh4534ever find the answers

[@gloriamariadc7757]

Can u do a vid on th other options on cold card.. what does th other stuff mean I’m th options lists.. it’s not obvious for a newb.

[@InspectorApe]

Can you make this wallet a just a read wallet?

[@jennysoapdish4502]

Sparrow wallet app 2.0.0 crashes overtime I try to scan a QR code. I am using MAC OSX. so frustrating.

[@Caring.for.Couples]

Why Bitcoin Well or Bull Bitcoin?

[@weslee511]

Can a low end desktop cam read qr code displayed by coldcard q? Phone cams seem to have no problem but pc webcams cannot

[@weslee511]

I saw at min 51 you were able to use can from pc but assume the webcam on apple is far better than typical with windows pc. Have you tried with a low end windows webcam?

[@VamosViverFora]

@@weslee511Low end laptops webcam usually can read QR codes. If you’re not able to, you may use SD Card for while.

[@eheffrey]

Say I do the QR air gap with phone and Nunchuk, and nunchuk goes defunct, I’d be fine right?

[@recongraves]

Same question

[@InspectorApe]

Yes will be good, the public key is used for app to create a transaction , but you still need the private key the device to sign the transaction to move the bitcoin period. The main thing is not to share the 12 or 24 word with an internet device or camera or Bluetooth . Then you’ll be safe. Those 12-24 word can be put into any hardware wallet if you break or lose the device . Those are your private keys so don’t lose those. Also good practice to have multiple devices with the same private keys as a backup.

[@gloriamariadc7757]

Can u do a vid on what u would do if u were to move to another country.. what u’d do as in.. empty cold wallet ? What’s th minimum items u’d need?

[@martinflo]

What if Coldcard where hacked and you downloaded malware on to your coldcard?

[@VamosViverFora]

You can do that (the signature) in a offline desktop and then generate a new QR code and then scan it in an online machine if you want. You’re right: don’t trust, verify.

[@recongraves]

Dark Skippy just came out seed hack watch out

[@AndyCreed0x]

I wonder what’s in the “I’m a developer” menu

[@P1kkaa]

idk if anyone can help me, but i did everything corretly, besides the address check, i checked my payment address just to fully understand, but i got a different result, instead of saying it's my address, it said its an unknown address, even tho i did a test before with a few sats, and than i send a larger amount, everything went fine, but my CC still tells me the address is unknown. does anyone kno what it may be happenning? thank you btc session, another great tutorial.

[@ГуглЭдвордз]

looks like the first prototype of the blackberry bold 😁

[@gh4534]

Does anyone think it would be a good option to have an MK4 with the QR reader but without the keyboard?: Is there a real need to have a full keyboard?

[@BTCSessions]

Honestly the full keyboard makes things a lot easier for me. Entering passphrases, recovering from seed, importing tapsigners with the description key, and plenty of other things are expedited quite a bit.

[@gh4534]

Thanks. That is what I was looking for. Even though I don’t plan to do many transactions, mostly hodl, I was not sure how the keyboard helps.

[@Kukulkan_Tours]

Smart to keep 4btc on one wallet or no?

[@recongraves]

No

[@recongraves]

You would rather have multiple entry points for one single exit point from your wallet is all seen on chain so people can Target you. Do you use tumblers lightning channels and certain other ways to mask your visibility

[@fwtt]

The discount link is broken!

[@392Caffe]

Why Nunchuck? What happens if Nunchuck is no longer available in the future? (Sorry... Newbie)

[@JakeyJay26]

You would have seen in the video that the wallets he used Nunchuck and Sparrow) are really just browsers to the same source of information which is the blockchain, so if Numchuck go out of business you’d just set up another wallet. In this video he imported the wallet using the QR code into both wallets. Maybe watch the video again with this context if you’re still concerned.

[@recongraves]

​@@JakeyJay26thx u

[@AshEllieRose]

Hey Ben can you do a bit box tutorial please with Nunchuk? Thanks ❤

[@GarryGarryson2022]

How can I be sure that there is not a hidden wifi radio built in!?

[@recongraves]

😂😂😂😂😂 buy a Wi-Fi scanner and go to the woods

[@JASONA55]

Are there any disadvantages to using batteries long term? Thinking about leaks and corrosion.

[@Insomniacs89]

Just 2 questions if anyone can help me ( sorry newbie here) : 1. What do I do if I wanna check the balance every now and then 2. What's the safest or air gapped way to install or update the firmware Thank you

[@drackotheguitarist]

Just in case anyone encounters this problem. When I tried to attach my MicroSd card to my Q1, It was not reading it. I had to format the SD card from within my Q1 and it worked.

[@jybevox]

REMEMBER, 12 WORDS IS ENOUGH Because Bitcoin elliptic curve security is only 128 bits anyway, as Andreas Antonopoulos and Adam Back said. Using 24 words is like typing a 100 characters long password, when the machine will check only the first 20 characters of the password anyway.

[@jybevox]

@@mattkwarren 12-word is easier to learn by heart and to write-backup.

[@mrprfct7069]

Buyers beware. I put in a reservation with this company for the presale of $199 back in April 2024. Somehow CK charge my card but they lost my reservation. CK finally found it after 4 months of back and forth but I know have to pay the difference an extra $20. What’s the point of reservation if they aren’t going to honor it? Plenty of other options out there.

[@unusual_Hodu]

thank you bro

[@Hasan-jf7by]

I still prefer Blockstream Jade! 👍

[@Eman1900O]

They had their customers’ emails leaked though. Other than that it’s great for the price

[@drackotheguitarist]

Just wanted to add that these aren’t available for immediate shipping. I ordered mine a couple of days ago and was told that it can take up to 2 months to ship.

[@miguelmacias8031]

Could we use Shakepay instead of Nunchuck?

[@cheebug]

20% discount on Q today cuz Germany is selling!!!

[@markanderson4353]

This is why Bitcoin will never become mass adopted. Your average person isn't going to understand the hoops they have to jump through to keep their Bitcoin safe or to send and receive it. Or they are going to lose their BTC through user error.

[@mithunphilip]

If adoption means investment - then ETFs solve the problem. If you mean usage as a medium of payment, technology keeps evolving, better solutions will emerge to make Bitcoin more idiot-proof.

[@CalvinGroover]

Well then those people who don’t learn will be destined to continuously be wrecked by the traditional financial system. You have to adapt to survive

Nice I got cool words in my seed phrase, what 12 words did you guys get?

[@NOSFERATU_ONE]

what a cheap ass looking box By God

[@dionbilous3494]

Maybe don't buy it in the first place. The company is not ethical. They lie about what they have in stock and actual shipping times. Bitcoiners should reject these practices as most of us have adopted BTC for ethical reasons
