FYI, You can no more mine ethereum after the complete roll over of ETH2.0 because the stake validators will be validating the transactions instead of miners because ETH is transferring from POW to PoS. You can continue to mine ethereum classic once you cannot mine ethereum and lot of altcoins are possible to mine with GPU.
Does Ethereum Classic have bright future like Ethereum (original)?
As for other altcoins,from what I heard,there will be shift from strongest coin to another,just like Ethereum inherit Bitcoin.
I heard that there will always be one or two coins that will be strong as Bitcoin and ETH are now,it's just we can't predict that what exact coin that will be.
Is it true what they say about that,and does that mean I could have same profit as I have now ($150-$200 monthly) with RTX 3080,just with different coin?
And if that's possible,will that last for 2-3 years with my current GPU?
One thing I learned is that cryptocurrencies world is all about speculations and there is no definitive answer,but I like to hear anyone's opinion as well as yours.
It may have a future but we don't know how long it is possible to make profits from ethereum classic as well but it is the next best option since it is having real market value rather than wasting your electricity bill to mine shitcoin which is having no value at all.
