Not sure how the BIP39 passphrase protected mnemonic code would not reveal your balance. Care to explain this? Thank you.
You can set a password (for instance in Electrum) to extendt he mnemonic. So with just 12 words, you'll find your daily spending money worth 2 pizzas. But if you add your own password to the 12 words, you'll get your fortune worth 2 airplanes.
