$ETH exchange supply has dropped from 3.56% to 3.20% since October 28, but the decline happened in two separate stages.

The October 29 drop partly aligns with the Binance hack, while the larger 313K ETH decline came on November 1–2 after withdrawals reopened.

Top exchange-address holdings are now down roughly 297K #Ethereum . Whether those coins moved to cold storage or other platforms remains unclear.
