Systems and methods of forensic analysis of cryptocurrency transactions are described herein. A method can include obtaining fiat-based transaction data from a bank account, identifying a purchase of a cryptocurrency from fiat-based transaction data and cryptocurrency exchange trade history data from a cryptocurrency exchange where the cryptocurrency was purchased, obtaining cryptocurrency-based transaction data that identifies downstream cryptocurrency transaction data where the cryptocurrency was transferred out of the cryptocurrency exchange; and scoring a user who purchased or used the cryptocurrency based on the fiat-based transaction data, the cryptocurrency exchange trade history data, and the cryptocurrency-based transaction data.
