Practice OPsec and keep quiet 🤐 🤐 🤐 🤐 about your Bitcoin.
even good opsec has a blind spot once someone is physically forced to move funds
when a transfer happens under duress, it looks completely identical to on-chain to a normal withdrawal. theres no way for a block explorer, an exchange risk system, or anyone watching the chain to tell 'user sent this willingly' apart from 'user sent this with a gun to their head'.
thats why the practical mitigation people in the physical-security space actually use isnt something that happens after the fact, its duress PINs/decoy wallets on hardware devices. enter one PIN, see your real balance. enter a different PIN under duress, and it shows a smaller 'sacrificial' balance while the real funds stay hidden under a different derivation path. the attacker gets something, doesnt know theres more, and you keep the rest
