Let's talk about passphrases for recovery phrases.
According to BIP-39, a wallet seed is generated from a recovery phrase and an extra passphrase using PBKDF2 with 2,048 iterations, producing a 512-bit result.
One point worth thinking about: the purpose of the extra passphrase is that even if someone gets your recovery phrase, they still can't access the wallet that actually holds your assets without the extra passphrase.
Write down the extra passphrase separately and store it apart from your recovery phrase. Don't write them on the same piece of paper.
The coin in the example: $BTC , current price 65,350.01, 24h -2.61%.
