I think this is not development or technical but bitcoin general discussion.
nevermind.
You can place 2 passwords on a Trezor and disclose only one.
But there is still the possibility that they kindly ask you about "is there more"
so best is, do not disclose your bitcoin.
Its like do not disclose if you won in lottery.
This is the most sane thing to do, however there is a problem: If you become rich, you are going to want to buy a nice house, and owning a nice house puts you a target as "someone that has money", so you are at risk already. Of course if the thieves don't know you don't own no BTC the wouldn't typically ask for it, but what im saying is, there is no free ride, unless you decide to be rich while having a poor lifestyle to not become a target, but who the hell wants to live on a shithole when you can just move into a better neighborhood. Hire guards to protect your property, what can I tell you?
As for having 2 passwords that disclose different amounts, I haven't looked into that, but it's possible. Then there's also perfectly possible you have passworded stuff that you legitimately forgot. For instance I have some encrypted hard drives that I cannot access because I forgot the passwords, so if someone wanted to access and was hitting me with a wrench it would be useless since I just don't know the passwords.
So basically, either keep a low profile or hire physical protection from criminals trying to steal your money.
