Mining is another type of investing after all. With ETH as already said, this is impossible because they are not giving away ETH as they used to, through mining processors. But still you have a ton of alt-coins that accept mining protocols.
If you start mining an alt-coin you are going to be putting your money (hardware, electricity, your setup time cost, etc...) into that shit coin. Generally the wrong thing that most miners have been doing historically, is calculating gains with the current price of the coin. But after all , like when you invest in any other coin, you must due your due dilligence. So essentially, coin mining is not dead, but is an investment like anyother, I would recommend doing at least 1 in life. I've been mining from BTC back in 2012, to Ethereum and Monero, and many alt-coins like Electroneum, with both GPU and dedicated miner-rigs. Nowadays it's too much of a coinflip exactly the same as crypto investing (in the past mining Bitcoins when it was at $500 was a brain-dead earning system, you knew you will earn each single penny invested on the mining rig + good profits).
Conclusion: Yes is possible, but due an extensive due dilligence.
