I’m trying to understand how people handle Bitcoin inheritance without giving a third party enough information to steal the funds while the owner is alive. A will can say who should inherit but it cannot recover a lost seed phrase. A seed phrase shar...

With newer cold wallets offered every year, does it make sense to move funds to these cold wallets especially when better security protocols are introduced. Older wallet models may have obsolete support also. submitted by /u/RockHardTen...

I’m currently using a Jade with a 12-word seed phrase, an additional password, and 2FA. The recent Coldcard incident made me rethink my security setup. Curious to hear how others are securing their cold wallets and whether you think this setup is eno...

In 2016 I was using a pre-generated physical Bitcoin paper-wallet card sold under the “Coin Cold Card” branding (coincoldcard.com was printed on the card). The public address was printed on the front. The private key and its QR code were printe...

So I had a bit of a wake up call today. With all the recent Coldcard drama, i started rethinking my own setup. I was planning to improve my custody a bit: add a strong BIP39 passphrase and eventually move toward a more robust multisig setup. Before d...

As someone that owns a Ledger Nano S+, would you say there's any need to switch to a Trezor (either a Safe 5 or 7) now or just stick with what's been working? submitted by /u/Candid-Walk-6762 [link] [comments]

I’m sorry but everything seems to be getting compromised and hacked rn. I’m sure I’m not the only skeptical one right now but I figure I ask for some input. Thanks Edit: I do cold storage but rethinking everything since these hacks continue s...

A pure 40-bit Coldcard seed wasn’t really cryptography. It was just a huge list of 1.1 trillion possibilities. Once the first serious attackers had working code, it was pretty clear what to do: finish the list. There was a small space, enough money,...

I started accumulating back in 2020, saved heavily and convinced my wife after realising that Bitcoin is the greatest monetary system and store of value that we should go all in. Got up to 5 BTC at my peak in 2021, and that’s when greed kicked in. I...

I like Matthew Kratter, but this is just sad. Don't give up brother, stick to your LukeJr chain and don't ever download the dirty Blockchain ever again. All that buildup for months just to give up in hours is beyond pathetic. sub...

After reading about cases where weak entropy led to unsafe keys and people losing funds (recent bitcoin COLDCARD attack) , I decided to learn more about entropy and how it is generated. There are different ways to generate entropy, like TRNGs,...

Verification because this sounds unreal: Privacy Guides and The Hacker News both covered it at the start of August 2026 — attackers drained thousands of ColdCard wallets for a total of ~1,367 BTC (~$89M). Root cause: a firmware bug from 2021. During...
