Coinone, South Korea's third-largest cryptocurrency exchange, has dismissed rumors regarding the sale of its stake as "completely unfounded." The exchange clarified that while it has received various collaboration proposals from both international exchanges and domestic companies, these are merely in the exploratory phase with no concrete deals or negotiations underway. The speculation surrounding a potential acquisition led to a temporary surge in the stock price of Coinone's second-largest shareholder, Com2uS Holdings, which holds a 38.42% stake, with shares rising over 17%.
