Cool experiment. But I don't recommend getting into Ethereum mining now, as the network is on the verge of switching to Proof of Stake as part of the migration to Ethereum 2.0.
Meh, it hasn’t switched yet, there’s still mining to be done.
I made ~$100 in the past month (stopped during the cold snap/storm here) on my 3080 mining ETH. Of course, I was getting closer to 90Mh/s so slightly more viable.
While I'm optimistic on PoS and excited about Ethereum adopting it, I think Bitcoin and PoW are being unjustly demonized and the issue is far more complex than what meets the eye.
There are a few (mostly Bitcoin forks), and you can probably make some profit mining them, but they are not big enough to have a significant impact on the global demand for GPUs.
At this point, most crypto projects with any real traction (with the obvious exception of Bitcoin) are either ERC-20 tokens running on Ethereum, or other PoS chains that claim to be better than Ethereum (i.e. Cardano).
As I said, there are plenty of profitable coins for GPU mining besides Ethereum [0]. Ethereum moving to PoS will not move the needle, people will just move on to something else.
