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.
