I have a question regarding BIP-32 and keys.
Imagine a scenario in which a user creates a new Bitcoin wallet with a seed phrase. He then generates a new address and sends 1 BTC to this address.
Under the covers, my understanding is that a master private/public key will be created from the seed phrase. Then, a child key is created under the parent key for the address.
Now, suppose this user completely loses their seed phrase / master keys, BUT they somehow have a copy of the child key pair that contains their Bitcoin.
Is it possible to recover their Bitcoin from that child key alone? If so, what is the process? Are individual child keys just the same as normal (non BIP-32) key/pairs?
Thanks!
