As the DAG file size of ETHW has exceeded 7GB (and is projected to reach 8GB in December 2027), some miners with insufficient VRAM, such as Antminer E9 and E9Pro, experience significantly hashrate reduction and fail to achieve the miner’s rated hashrate.

So many ETHW miners switched their hashrate to ETC, you can see mining difficulty of ETHW has dropped wildly, don't miss your opportunity if your miner are able to mine ETHW.
