With the recent switch of Ethereum (ETH) from Proof of Mining (PoW) to Proof of Staking (PoS) there was a big change in the crypto mining landscape. There was an enormous mining power consisting of a lot of Ethash-based ASIC miners and even more GPUs having to be switched to other crypto currencies and nothing else could handle so much computational power being forwarded to it’s network without significant increase in difficulty and thus a huge drop in profitability. Now, a few days later there is still pretty much nothing that can be stably mined with GPUs at a profit, even covering for the electricity that mining GPUs use with what you mine is still an issue. People are wondering and asking What to Mine, but nothing is really profitable yet, though if you are willing to cover your electricity cost and save what you mine in crypto for now there are a lot of options available.
Ethereum Classic (ETC) is one of the obvious choices when it comes to switching your mining hardware from ETH after the PoW to PoS switch happened, as it is easier and familiar, but profitability wise is it not among the coins that currently bring you the least loss (in term of revenue). There is however something that you can do in order to improve the situation a bit and that is to Dual-Mine ETC and Zilliqa (ZIL), similar to previously doing the same with ETC+ZIL Dual-Mining. Currently the reported extra profit from ZIL is around 30+ extra percent compared to just when mining Ethereum Classic (ETC) on its own, though that value can vary and be even higher at times, so definitely worth checking the Dual-Mining option if you are only mining ETC at the moment. Of course even this way you are probably not going to even fully cover the electricity costs, but 30% more is still 30% more, so you can only gain extra and not loose anything if you are solo mining ETC.
