On 3 November 2022 at 12:00 UTC, BitMEX will change the Mark Method for ETHPOWZ22 from Last Price to Fair Price. We are able to do this because we have now constructed a robust index that represents the spot price of the ETH Proof of Work Coin, the .BETHPOWT index, which incorporates the ETHW prices from Bybit, FTX, Huobi, Kucoin, and OKX. Please note that this will also mean the removal of Limit Down and Limit Up price protections. If you have any questions please contact Support.
