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

[@nonshatter7]

Excellent explanations to your tutorial as usual.

[@jybevox]

Looking forward so much to see this video :)

[@VamosViverFora]

Ben, you’re the best!

[@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.

[@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!

[@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?

[@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

[@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.

[@jybevox]

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

[@AshEllieRose]

Beautiful!! 😍

[@stevejacobson7431]

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

[@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?

[@eheffrey]

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

[@AshEllieRose]

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

[@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.

[@DouglasPorter]

How do I get the BBQr option? Sparrow only presents me a series of QR codes, which I cannot get the Q to read. I'm stuck!

[@unusual_Hodu]

thank you bro

[@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.

[@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?

[@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.

[@GarryGarryson2022]

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

[@Hasan-jf7by]

I still prefer Blockstream Jade! 👍

[@Eman1900O]

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

[@fwtt]

The discount link is broken!

[@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.

[@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.

[@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.

[@JASONAdam-tk1rg]

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

[@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.

[@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.

[@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.
