"The Legacy Archaeologist"

This character emerges in a tragic situation. They are the children or spouses of crypto investors who died suddenly. They know the deceased had billions of Rupiah in Bitcoin, but they don't have the Private Key or Seed Phrase. They turn into detectives who crack safes, comb through old notebooks, and flip mattresses just to find a piece of paper containing 12 passwords. They are legally legitimate billionaires, but cryptographically poor because the treasure is locked forever on the blockchain without an access key.
