@FP91G you do believe that the Ethereum POS is really coming and PoW mining will end? How certain are you? If this happens it will affect other coins as well because their difficulty will surge I doubt they will remain profitable
I think that in the 2nd quarter of 2022, Ethereum mining will end, or we will have more accurate information. If the current hashrate is directed to other coins, then the profit will fall by 5-10 times. I don't know what coin can replace ethereum, because over 80% of graphics cards mine ethereum.
