South Korea is weighing a much stricter rule for exchange custody — the Binance hack's first regulatory aftershock in Asia, as I see it. After its November 2 emergency meeting, the Financial Services Commission is considering lifting the cold-wallet floor from 80% of customer crypto to about 99%. That is not a rule yet: no threshold has been formally adopted and no timetable published, so treat it as a proposal under review, not a done deal. The gap it would close is uneven. At end-September, Upbit already held 99.17% offline and Bithumb 94.76%, while Coinone sat at 85%, DigitalX at 82.79% and GOPAX just above the floor at 80.54%. The honest catch, from Korean coverage of the meeting, is that a vault ratio alone doesn't stop a hack — Binance's breach came through staff computers with withdrawal approval, not through the vault walls. $BTC near $78,056 (+1.5%/24h) on Binance spot is context, not a reaction to this. If 99% becomes law, do slower withdrawals buy real safety — or just slower exits? NFA, DYOR. #CryptoNews #SouthKorea #ColdWallets #ExchangeSafety
