Odaily News @mononautical, the founder of mempool, posted on the X platform that all confirmed and pending wallet collection operations of OKX starting from block 846867 generated a total of 2,385 transactions, spent 357,092 inputs, consumed 103 MvB, and the average fee rate reached 246.65 sat/vb, with a total fee of 254.28 BTC (about 17.6 million US dollars). He explained that this seemed to be due to a poorly executed automated system that caused the fees to get out of control.
