Even better if you can use multiple different passphrases. 0.1 BTC on the seed phrase which you can give up under duress. If they keep hitting you, 0.5 BTC under an additional passphrase which you can give up as well. Meanwhile 5 BTC under a much stronger different passphrase which you keep hidden.
you got alot of people that merited this point of view but i'm not so sure i agree with the philosophy of having staggered amounts in various wallets. on one hand, i guess it could limit your losses if an armed thug is not so determined and happy with getting $2000 without really pressing you for more. but what happens if the 0.1BTC is not enough? how much are you willing to go through before you admit to the 0.5BTC wallet and turn that over? once they see that you're playing this game, the sky is really the limit and then the real risk becomes that they don't believe you when you say the 5BTC wallet was the biggest one you had because you said that about all the other ones too. then you're really in trouble. could be in trouble.
also i guess it goes without saying that you would need to have a way of memorizing and producing the passphrases in a certain order of increasing btc content value. another difficulty in this scheme.
obviously no one wants to give up a huge stash to the first thug that threatens them with a wrench but i say just have a 0.1BTC or 0.5BTC wallet and be done with it. that should be enough. unless they have a reason to believe you are worth far more...
