Method to protect your Bitcoin from a $5 wrench attack:
Run BTCapsule and create two wallets. One is timelocked to a future date you choose, and the other can be redeemed immediately
If a thief threatens violence, you can give them the timelocked wallet, and explain that you cannot access your Bitcoin. You can show them that the Bitcoin is on the P2SH address with a blockchain explorer. Explain that when the timelock expires, they will have your Bitcoin
When you feel safe, redeem your other wallet and put your Bitcoin wherever you want to
The thief wonโt know anything until they try to redeem the script and it fails
