Physical coercion — hardware wallet (2025)

Blocked
Case description
A Brazilian Bitcoin holder's family member was kidnapped in April 2025 and held for ransom payable in Bitcoin. The kidnappers specified the ransom must be paid in Monero rather than Bitcoin, demonstrating operational knowledge of cryptocurrency transaction traceability—specifically, that Bitcoin transactions are visible on a public blockchain while Monero transactions are private. The holder was forced to first purchase Monero on a Brazilian exchange and then transfer it to the kidnappers' wallet. The NBC News investigation into crypto kidnappings in 2025 included this case as an example of organised criminal groups demonstrating technical cryptocurrency knowledge to maximise their operational security.
