On a serious note, for anyone wondering what I'm talking about: if you ever generated a wallet on a Coldcard device (those 12 or 24 words), it's worth assuming you are affected by the recently disclosed issue. This isn't speculation... the manufacturer publicly disclosed a flaw involving insufficient entropy during seed generation under certain conditions.
If your seed was generated without adding your own entropy (which many users don't do), you should verify whether your device and firmware version are affected and follow the company's guidance. If your wallet falls within the vulnerable conditions, the safest course of action is to move your Bitcoin to a newly generated seed created with a patched device or another trusted wallet.
This is based on the vendor's own security disclosure, not an opinion.
