> Nobody can steal your bitcoin if your private keys are well protected. And of course, the best protection is a brain wallet. The end result of this is that a huge portion of humans cannot safely store their wealth in btc. I sure as hell don't trust myself to keep that much cash in a brain wallet. "If your private keys are well protected" might as well mean "if you can do four backflips in a row" to most people. |

You can leave a small amount of coins in the wallet using the same seed phrase but with no passphrase as a decoy. This way, if somebody "stumbles upon" your seed phrase, they'll attempt to recover this small amount of money, and you can monitor using only the xpub to discover it has been compromised. You then have some time to move the other coins before anybody could potentially brute-force your passphrase (Since they need to compute PBKDF2 for each attempt).
You can reuse the same seed phrase for multiple wallets, using a different passphrase for each. There is no way for somebody to determine if you have surrendered all passphrases for a give seed, since there could be infinitely many. This offers plausible deniability in the case your thief is the government.
