South Korea urges crypto exchanges to raise cold storage after Binance hack

The regulator's move is notable because it asks exchanges to go beyond a threshold they already satisfy, suggesting that meeting a minimum is no longer treated as sufficient after a major venue's breach. It affects domestic operators' custody and operational costs, and by extension how Korean exchanges differentiate themselves on safety. Whether the 80% rule becomes a floor that gets informally raised, and how exchanges respond in their cold-storage disclosures, is the open question worth watching.
