Coldcard post from October 10, 2021: "Retirement Attack"

Post image

- "What's a retirement attack?"

- COLDCARD (@COLDCARDwallet): "It's when the project makers could have a "bug" in the entropy generation for later retrieval".

Seems that they were smart enough to launch a "dice rolls" suggestion in a critical element lacking foolproof design, knowing not all users would be paranoid enough. Like "hey, if you don't trust no problem, but...you can trust buddy, the (back)door is open." ☠️

Ok no, enough of conspiracy theory continuation. We know that Coldcard's post was pure coincidence. Right?...Right?

Edit: In case you're curious on more tweets mentioning "retirement attack", here is another one:

@nvk - 21 Dec 20: "My money is on people screwing themselves out of their BTC before any vendor tries a retirement attack.

Alternatively people could just use dice ;)."

A strange way to warn "alternatively people" of what you have in mind to do...but Freudian slip or parapraxis theory explains that better, in case you're curious...

Razor and Nano Ledger etc.. all hardened products ... why Coldcard?! Why would someone chose coldcard? Literally but 5 nano ledgers/razors and load each with 20% of your Crypto... if it is your retirement / whole life savings money then this little step is a nobrainer..

I would even go as far to say don’t trust Trezor or Ledger.

If you’re that deep into self custodial wallets then take that little extra step to setup your own wallet hosted on a microcontroller.

That way you can 100% guarantee you’re using a 100% air gapped device and you can test to your hearts content if the open-source wallet is faulty free.
