Can bitcoind print out a BIP39 seed phrase to backup the wallet?
Can I import a BIP39 seed phrase (from, for example, Breadwallet on iOS)into bitcoind?
I know bitcoind wallets have been BIP32 format since 0.13, what is used as the seed? What is backed up when I make a copy of wallet.dat? If the wallet is encrypted, does the seed change (the way BIP32 uses a passphrase as "the 13th word"?)
