I'll be traveling to the United States soon, and I've read that civil asset forfeiture laws may allow customs agents to take/keep crypto currencies. Is there an easy way to keep my wallet safe from confiscation? I have a Trezor, but I'm not sure how best to travel with it. Should I keep coins on an exchange while traveling? Move them to a paper wallet or my laptop?
The Trezor (and other hardware wallets) use the BIP 39 specification for the recovery mnemonic. If your device is confiscated, you can use the recovery mnemonic to restore your wallet to another Trezor, hardware wallet, or software wallet. From there you can access your Bitcoin.
