Heads up — there's a serious Coldcard wallet issue right now. About 594 $BTC (roughly $38M) has been drained from old single-sig wallets.
You're at risk if:
• You set up a single-key wallet on a Coldcard Mk3 between 2021–2023
• You didn't use dice rolls, a passphrase, or multisig
If that's you, move your funds now.
The problem? An entropy bug from a 2021 firmware rewrite. Only affects Coldcard — Ledger, Trezor, and other hardware wallets are fine.
But honestly, don't panic and rush into things. That's when scammers show up. Take a breath, double-check everything, and move carefully.
