I think that PoW is no longer needed because we have PoS...
PoS is rewarding wealth. PoW is rewarding work.
Therefore PoS = Piece of Sh..
Iridium is PoW.
Those who want to see the fraudulent legacy financial system, where newly issued money goes to the billionaires/monopolists, the friends of the central bankers, and then eventually a tiny bit of it "trickles down" to their wage slaves, bering introduced in crypto too --> Support PoS coins.
Those who want to see crypto as a system where newly issued money goes directly to the workers (aka miners) --> Support PoW coins
I guess most of the kids who scream for PoS on this and other forums have no clue what that concept really means. I doubt they are rich, probably just stupid.
If you think about it, it's the same thing, you don't mine with your hand bro, you mine with your gpu,cpu or whatever, at the end of the day it's still money. They can have a big farm or they can buy coins, same thing it's still money. PoS is better in a sense that it does not allow big company like Bitmain to have asics for themselves (they usually mine with asics for months before selling them). PoS will prevent that.
