Bithumb, South Korea's second-largest cryptocurrency exchange, has announced the suspension of all deposit and withdrawal transactions related to the overseas payment platform Heleket. This decision comes amid suspicions that Heleket is involved in illegal activities such as money laundering and terrorist financing. The move is part of Bithumb's efforts to comply with anti-money laundering (AML) regulations and protect customer assets. The suspension affects all virtual asset transactions associated with Heleket.
