最新报道:Brazilian police arrested four suspects for kidnapping a retired teacher, mother of a crypto trader, demanding 5 BTC (over $600,000) ransom. The gang tracked the victim's son through social media, held her at gunpoint for 12 hours until the Portugal-based trader paid. Authorities noted difficulty recovering the stolen Bitcoin amid rising global "wrench attacks" – crypto-related kidnappings, including recent cases in London, France, and New York. A 2025 database shows such incidents nearly matching 2024's total already.
