These formats are primarily used to make it easy for people to read and transcribe keys without introducing errors.First, the tree structure can be used to express additional organizational meaning, such as when a specific branch of subkeys is used to receive incoming payments and a different branch is used to receive change from outgoing payments.

Importing a Bitcoin private key can allows to use a different Bitcoin wallet software or service without changing Bitcoin address.When the hardened private derivation function is used, the resulting child private key and chain code are completely different from what would result from the normal derivation function.
