The US FTC warns that Bitcoin ATM fraud cases have surged, with losses exceeding $120 million in 2023. Hackers and scammers steal funds and personal information by manipulating ATM equipment or network communications. Users are advised to be vigilant when using Bitcoin ATMs and avoid sending money to unknown entities. It is reported that 74% of the world's cryptocurrency ATMs are managed by only 10 operators. The largest BTC ATM operator, Bitcoin Depot, operates more than 8,000 ATMs and claims to have multiple verifications to prevent hackers. (CNBC)
