The Bitfinex theft became one of Bitcoin’s largest exchange-hack cases
The U.S. Department of Justice says a 2016 intrusion led to approximately 120,000 bitcoin being stolen from Bitfinex; funds were later traced and seized in part.
The incident connected exchange security, blockchain tracing and complex laundering strategies across years of investigation.
The case showed that public ledgers can preserve transaction trails even when stolen assets move through many services.
Blockchain traceability does not guarantee immediate recovery; custody security and timely incident response remain essential.
