[@RhettReisman]

Coldcard or ledger?

[@Royorg-qf5jq]

Coldcard

[@leandroalbero]

It’s quite obvious

[@yourdailydoseofcommonsense5495]

Bitcoin, not shitcoins. Other than that, solid video 🤙

[@RhettReisman]

Gang gang

[@dereksbooks]

I love Bitcoin only companies like Coinkite that are remaining faithful to the revolution and aren't selling out to cash in on the current lucrative trash known as "crypto" (centralized securities illegally masquerading as decentralized currency). Bitcoiners in turn should support Coinkite and other Bitcoin only companies.

Thanks Sam 🙏 glad to help

[@BreakNAllRecordsBARtv]

Great review Rhett. The BTC gas fees are close to Solona's LOW. Even ETH isn't that bad with ledger. Good to know the calculator only S/R 's BTC... Thanks for the video.

[@RhettReisman]

Glad to help! Yeah the fees are really low right now - gotta love bear markets eh?

[@sandipansaha5794]

Could you please make a video comparing coldcard vs bc vault?

[@RhettReisman]

What is bc vault?

[@johnroff2704]

I bought bitcoin using a Trezor. The Coldcard looks great! Trying to decide if I should buy one, I want to be clear as to where, precisely, the security risk is. Is the risk only when I'm connected to the internet, or is there still risk even after I've disconected from the internet? Thank you!

[@RhettReisman]

The non-airgapped wallet vulnerabilities are primarily present when the device is connected to an internet-connected device or network. When connected, the wallet is exposed to various risks, such as malware infection, remote attacks, and data leakage. There could be residual risks from previous connections but primarily the risks are higher when the device is connected. Overall I think these risks are small and that a Trezor is probably good enough. If you're storing a life changing amount of money maybe consider a multisig and get a coldcard.

[@johnroff2704]

@@RhettReisman Thanks so much!

[@RhettReisman]

Glad to help :)

[@smartbusinessltd]

What can you throw more light on air-gapped function

[@RhettReisman]

Here’s a setup tutorial where I use the COLDCARD without ever plugging it into a computer. If you have a specific question about airgapping like why it’s helpful or something let me know :) kzbin.info/www/bejne/j5aoqmqmhNeYZpY

[@smartbusinessltd]

@@RhettReisman okay thanks 🙏🏻

[@agolden24]

Could not charging your ledger after a significant period of time lead to it not working? Are these designed to last for 50+ years?

[@RhettReisman]

Over long periods of time the battery might not store a charge as well but it should be able to connect to computer. To your point, I think you should probably health check the devices every year or so and get new ones if you start to see something not working. I doubt it would last 50 years, but that’s why you have the seed phrase.

[@smartbusinessltd]

How often should I charge it and if I lost my ledger can I get another and just restore using my seed phrase

[@RhettReisman]

@smartbusinessltd Only the Ledger Nano X has a battery, you can charge it however often you want I never really charge mine. I just threw it in a safe place. If you’re taking it on the go often for some reason and you don’t want to connect it to a computer over USBC you could charge it more often And yeah if you lost it you can restore to another ledger with your seed phrase

[@smartbusinessltd]

@@RhettReisman thanks for your reply… means alot especially in such a time

[@RhettReisman]

No problem man 🙏

[@Jaytraveler2]

What about blackstream jade wallet vs cold kite wallet?

[@RhettReisman]

Haven’t used Blockstream jade yet. It seems like a slightly different offering from all these other hardware wallets. The Blockstream jade people seem to think it’s the greatest thing of all time and some hardcore bitcoiners seem to think that it’s dependent on an internet connection or a satellite connection or something for it to work. I don’t really know yet haha

[@Jaytraveler2]

@@RhettReisman The reason I was looking into those two particular because they're both bitcoin only wallets. I appreciate your reply and information regarding being connected to the internet with the Jade.

[@rufuspipemos]

Recommendation.... do a video that basically shows your viewers.... "Do these things before using a non-air-gapped wallet." For example, should I install malware blocking software or other security software, first? Do I need a password manager before using one? Should I get a new modem? How to make firmware updates more safe, etc. Since most don't want to go through all the steps of the ColdCard, is there a way to make using a Trevor of Ledger more safe? Thanks.

[@RhettReisman]

Sorry for late response. I would always have a malware blocker and a password manager. You can delay your firmware upgrade by months to get a little more balance on security if you're worried about a rogue firmware update. Overall I think the best solution is to just use a multisig like Casa or Unchained then you're insulated from the risk of a single hardware wallet.

[@Stinabean12]

Can you factory reset your cold card? Say, if your seed becomes compromised and you need to generate a new seed, do you have to buy a whole other cold card or can you wiper the one you already have? Ledger nanos can do this

[@RhettReisman]

You can factory reset and generate everything again from scratch just like a ledger :)

[@Stinabean12]

@@RhettReisman why does the cold card say over and over there is no factory reset? I’m just trying to understand lol

[@RhettReisman]

I think they mean no factory reset IF you lock yourself out by forgetting your pin. But if you can validly login to the coldcard you can reset it

[@w3llsmith165]

Looking at a source code is useless without compiling and flashing on your own cpu.

[@RhettReisman]

Instructions to verify the source code is the same as what is on your device here: github.com/Coldcard/firmware

[@lennybrewster4673]

That nano x not looking so good anymore as of last week lol

[@RhettReisman]

Talk about it king 🗣️ Tbh, from a security perspective, it was never close

[@wesleymitchell7275]

Don't be a crypto gambler with a ledger. You might feel safe, but really their storing all your data. The cold card is the way to go. Air gaped, Bitcoin only, and way more secure. He made a point about password management, the cold card can do it and store up to 999 of them. And can have up to 999 wallets on it. Be a stud get the cold card.

[@RhettReisman]

99% of the ledger fud is fake news. Both devices are great :)

[@EternalStudent7]

Both. Coldcard for BTC and LEdger for shitcoins..

[@RhettReisman]

This is the way

[@dlukton]

Yes; especially now with the recent revelations from the Ledger company.

[@choosefreedom7585]

Bitcoin only

[@RhettReisman]

🔥🔥🔥

[@lideadhead]

Take your bitcoin off the exchanges they said. I went the ledger route, moved some of my btc to the wallet and got ripped off by ledger. Coinbase charged me $.83 and Ledger charged me $15.95!!!! That's ridiculous. Does Coldcard charge the same outrageous fees? Why even charge $150 for a wallet if your just going to rape us in fees to store crypto on it?

[@RhettReisman]

Ledger charged you $15 to move your funds out of ledger? Maybe the on chain transaction fees were high when you were trying to move your funds. Ledger shouldn’t be charging you any ledger specific fees

[@markxsavage]

That doesn’t sound right, Ledger charging you to move funds from Coinbase to your Ledger wallet.

[@lideadhead]

Oh it's true. Many transactions. I have the receipts to prove it.

[@lideadhead]

@@RhettReisman I'm not moving Ledger to CB.

[@RhettReisman]

I’ve never seen ledger charge a fee, feel free to dm me the screenshots on Twitter though @rhettre and I’ll see if I can provide some insight
