According to Bloomberg, Japan Exchange Group (JPX) is considering stricter rules to curb “coin-hoarding” listed companies, known as Digital Asset Traders (DATs), after heavy retail investor losses. JPX may tighten backdoor-listing enforcement, mandate re-audits, and restrict financing for firms prioritizing crypto accumulation. The exchange has already asked three prospective DATs to pause listing plans. Japan currently has 14 publicly traded Bitcoin-buying firms—the most in Asia—with Metaplanet, the largest, down over 75% since June.
