U.S. Seizes Bitcoin Mining Machines Over AI Chip Concerns

U.S. Customs and Border Protection (CBP) has expanded its crackdown on Bitcoin mining ASICs, seizing devices from MicroBT, Canaan, and Bitmain at the request of the FCC. The issue stems from AI chips in these machines that lack FCC approval. Previously, CBP only targeted Antminer models, but now multiple manufacturers face customs clearance delays at various U.S. ports. Some firms have lost millions in seized equipment, and affected companies are considering legal action. With the crackdown widening, major mining hardware suppliers are struggling to navigate increasing regulatory scrutiny.
