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...

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...

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...

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...

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...

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...

The biggest lesson BTC taught me is that if I plan to hold it for years, the daily chart should not affect my decisions. I still check charts sometimes and adjust the amount I buy based on the price that day, but I'm not to treat every red or gre...

Coinkite needs to entice the hacker to become a white hat, by returning the funds in an organized way. If they offered 10% -?% (after costs are deducted) of the value swept back I am pretty sure the hacker/hacker would prefer to avoid the headache o...

This SparkKitty malware can scan ur phone's gallery, find seed phrases in photos, and send them to attackers. Crazy part is, infected apps even made it onto official app stores. Keep ur seed phrase offline, delete any screenshots and check which...

Today's episode literally killed the faith of several hardcore old time bitcoiners and I'm shaken too, not going to lie. Even more than the FTX collapse. Why? The mantra "not your keys, not your coins" was already widely spread out...

I don't know Coldcard but it seems from what I've read of the exploit, it's because they let the computer generate the random seed and not use anything outside the computer's software. This is kind of unimaginable to miss at the first...

It’s remarkable how quickly the network responds to a known vulnerability. "Spend" is a catch all I use on this chart for any Bitcoin movement. It's volume really. PnL is how much the value of every UTXO the last 12 hours has chan...
