I still see a 196k CLAM volume spike on the 1mn chart at 20:34 UTC tho. Price fell from 231k sat to 180k sat in that minute. Average price should be >200k sat which gives us >400 BTC in volume. I hardly believe simply pulling the buy wall would instantly trigger a 400 BTC vol surge in under 1mn. Either the whale sold into his wall, or another person did.
You may be right. I saw the price drop when it happened and the reported volume was still very low, but I think that may have been lagged.
