OK, $5 wrench will crack all, unless you sacrifice your life.
This is why you never keep all your crypto in one wallet. Split your coins up between a number of wallets, using a number of different mediums. Keep some of the wallets entirely hidden, for example by using a passphrase on top a seed phrase which has some coins stored in it, or by creating a hidden encryption volume, and putting one wallet in the non-hidden volume and a different wallet in the hidden volume. If you are a victim of a $5 wrench attack, you can hand over one or even several wallets which each contain a relatively small amount of bitcoin, while your main wallets stay hidden. If you do this, you need to make sure there is no obvious blockchain link between your wallets as well. If the wallet you hand over showed 5 BTC moving in a single transaction to a single address, and the coins haven't moved from that address, then that is a dead giveaway.
It wouldn't help. $5 wrench would always know the exact sum you possess. He doesn't come at random and blindfold. If you deal with the excessive amount of crypto all your data are already in databases of the various 3-letters agencies and it is only the matter of time when they will be at the hand of $5 wrench.
