TechFlame reports that according to Cryptonews, Seoul's Gangnam-gu district is stepping up tax enforcement actions against cryptocurrency holders. Since the end of last year, the district has recovered around 3.4 billion won (about $24.5 million) in unpaid taxes through cryptocurrency seizure. Gangnam-gu has cooperated with five major cryptocurrency exchanges in South Korea to seize cryptocurrencies such as Bitcoin to recover unpaid taxes. District officials said that many residents have large amounts of virtual assets, and after seizing these assets, the voluntary payment rate of unpaid taxes increased significantly.
