But, I agree, a PoW coin SHOULD have a more value because it's some work done that isn't for free. But that's no guarantee ofcourse, I have mined ZCL in 2018 and they are almost GONE. Some other coin like SnowGem also, GONE.

That is what scammers have been doing since 2010, create new coins from thin air then market them and then dump them prior bullrun ends, repeat next cycle.
