SHOOT THESE

SHOOT THESE (and sleep like a baby). Thank me later. I genuinely hope Coinkit files for bankruptcy. They should have no business staying open after what they did. A few weeks ago, I thought about moving my funds to a Coldcard thinking it was sa...

Can hackers know you use a passphrase?

With this cold card complete disaster, I'm wondering how much security a passphrase adds? Can a hacker know that a hacked wallet has a passphrase associated? My understanding is that the passphrase wallet is completely new from the original walle...

Open source wallets question

The bit argument for open source wallets was always if there’s a bug the community will catch it. How come with the Coldcard bug no one was able to spot it before it happened?? submitted by /u/nick_c8_vegas [link] [comments]

So this hack was via China's LLM apparently

From what I just heard on Natalie Brunell's podcast, this was caused by someone using China's brand new LLM that ripped off code from Anthropic. It has only been out a few days. Unlike Anthropic the China model dows not have any safeguards ag...

“I lost my bitcoin in a ColdCard Accident.”

@WhiteRabbitBTC produced official Bitcoin Boating Club membership cards back in 2018-2023. Wish he was around for this to do an updated version. submitted by /u/gettxoutsetinfo [link] [comments]

The Biggest Coldcard Bitcoin Theft Didn't Break the Wallet But Recreated Their Keys

Yes, it is actually difficult to secure your seed.

Really sorry to hear what happened to many Coldcard Mk3 users. You did nothing wrong. To get the obvious out of the way, the hate Coinkite is getting right now is deserved. Firstly, there should have had a more thorough review process that would have...

They stole the BTC- now what?

The ColdCard hack has seriously shaken the BTC community in less than 24hrs. Very disturbing and disappointing. I went on a block explorer and checked out the thief's addresses (now there are 2). The whole world is now focused there- are coinjoin...

I am going to be a contrarian. It's okay to buy the ETF.

If somebody is new to this market and just cares about price exposure, I'd argue them owning shares of an ETF is more safer and practical than owning self custody BTC. I don't think Blackrock or any of these multitrillion corporations are sc...

Best Cold wallet

Needing to set up a cold wallet. Any advice of what to be looking for? submitted by /u/Ok-Crab-567 [link] [comments]

Laziness Helped Me Dodge a Bullet?

Owner of a Coldcard MK3. I've always hated updating devices, my coldcard included. My MK3's firmware is still 3.1.9 . Coinkites reponse says 'the issue relates to Coldcard Mk3 firmware versions 4.0.1 through 5.0.3' 1) Does this mean...

I haven’t touched my coldcard since 5 years. Can someone help ?

Hello, I have an mk3 which I haven’t touched since like 5 years and would like to move my funds to a different wallet. I have created the seedphrase with dice rolls but I don’t remember how many times I rolled and I also added a passphrase. I feel li...

Coldcard, fuck yourself.

That is so unbelievably stupid: https://preview.redd.it/fvg49i64mlgh1.png?width=617&format=png&auto=webp&s=10910218d099199dcce3972df1bee5826db902c5 https://primal.net/e/nevent1qqsxt6lahxeq8h69ne78w6ls394ez5pqycguwrsp89tacwteh7878ccm...

If Coldcard acknowledged the seed generation flaw, shouldn’t they reimburse users who lost BTC?

I’ve been reading about the recent issue where researchers found that the seed generation on certain Coldcard Mk3devices wasn’t as random as it should have been, making it possible under certain conditions to derive affected wallets. This got me thin...

Unbelievable that redditors were recommending Cold Card!

Coinkite (the company behind Cold Card) has 2-10 employees according to their LinkedIn Page. Their venture capital funding (tracked by PitchBook) is listed as $122K, while Tracxn logs it as $115K. This is a boutique shop, essentially a mom and pop es...

Unpopular opinion: self custody isn't right for everyone, here's my story.

With the whole Coldcard thing that just happened, figured it's worth sharing my own experience, even though I know this isnt gonna be a popular opinion here. Back in 2024-2025 i sold off the bitcoin i had left (did a full cycle, accumulated in th...

Is there a final number of how much BTC was stolen from the Coldcard hack?

Just curious about this. submitted by /u/Sweet-Celebration498 [link] [comments]
