You arrive at a wizard's lab. These wizards are making hashes from preimage data. You look at your coin and you wonder what from this coin can use as a preimage. Maybe we should try hashing things from the coin and appending the first 3 bytes of a digest to our path.

note: 3 bytes = lowercase hex (6 chars)

A wizard looks over at your coin. "By the way that looks like it's delimited by an LF".
