PoS is just centralized fake my friend. Ethereum is not real anymore.
PoW is real and PoW only. Bitcoin is slow PoW. And Kaspa is fast PoW. Kaspa is Bitcoin 2.0
You can call PoS centralized or whatever you want go ahead. But let's not act as if Kaspa is the first blockchain to sacrifice decentralization for more speed even with PoW.
You know what's funny? I don't think Kaspa is even trying to go against Bitcoin. Kaspa is a smart contract platform.
