If you want to mine them, there's a list of new ones in here
https://miningpoolstats.stream/newcoinsBut i honestly think that those are not going anywhere, because of the propaganda you mentioned, and the fact that you can't trade them in dexes. If they don't have any funding they will be listed on some random free CEXes and won't get any traction.
And i disagree with PoS centralization, especially against new PoW coins that are mined in 2 mining pools and can be easily controlled just one mining farm. And stuff like that. Not every solution needs a new chain.
I'm surprised there are so many PoW coins out there, when there's so much propaganda against them (particularly by mainstream governments). It looks like PoW won't become "extinct" anytime soon. Unfortunately, most of the projects found on the link above don't bring anything useful to the world. They're clones from one another. Anyone who mines these coins would only be doing it for fun. Not to turn a profit.
Let me tell you, PoW is decentralized but that doesn't mean it's perfect. PoW can be compromised if only a few players (such as mining pools) control 51% of the network. Bitcoin SV is a good example of a PoW coin that's highly-centralized. Maybe hybrid consensus mechanisms (PoW + PoS) are a better solution?
Kaspa is what I am seeing that's commonly suggested by other altcoin miners. The other one that I am seeing is ravencoin which has the algorithm of KAWPOW.
That's the two that are I am seeing and being mined by many miners these days. About the profitability, I don't know but if they're mining it and they think that it has got a bright future.
Prolly, on the next bull run they're all just covering all the mining expense and stacking the coins they mine for now.
The good-old Ravencoin is still "kicking" after all these years. I like the fact that the project constantly changes its PoW algorithm to remain ASIC-resistant. Sort of how Monero and Vertcoin are doing today. This enables higher decentralization, as nearly everyone has access to either a CPU or GPU. In countries where crypto is illegal, obtaining and running an ASIC mining hardware could be quite challenging. Coins like the ones mentioned before would allow people from such countries to mine "under the radar".
Either way, expect PoS coins to become the majority due to false propaganda from mainstream governments. I wouldn't worry about this as long as decentralization wins in the long run.
