A California man alleges attackers used an unauthorized SIM‑swap in December 2021 to take about $100,000 in bitcoin from his Coinbase account; his lawyer traced the funds to a destination wallet and obtained a federal judge's permission to serve the anonymous wallet by embedding a summons link in a $100 bitcoin transaction using an OP_RETURN message. The article reviews legal precedent and expert views on tracing and recovering stolen crypto, the potential for default judgments against anonymous wallets, and the broader implications for victims pursuing civil remedies when law enforcement action is slow or unavailable.
