anchored·5P4BBT…Sq21Summary
Coinone is a South Korean cryptocurrency exchange founded in 2014, ranked among the country's largest licensed trading venues. In April 2026, South Korea's Financial Intelligence Unit (FIU) fined Coinone 5.2 billion won (about $3.5 million) and ordered a three-month partial business suspension over alleged anti-money-laundering and identity-verification failures, though a Seoul court later stayed enforcement of the suspension pending litigation. The exchange has also been the subject of a 2023 criminal case in which former listing executives were convicted of taking bribes to list tokens, and a 2019 court ruling that held it partially liable for customer losses in a 2018 hacking incident.
