I think PoW will fade as PoS continues to prove superior in scalability with higher transaction throughput. It is better to save money on GPU and CPU, I would recommend looking for PoS cryptocurrencies like DIVI that offers us Masternode with a really easy click or configuring Staking very easily to get 20% performance, the value of the coin is ideal, this year @Diviproject will surprise us with their new collaborations.
That's bullshit, PoW algorithm is better in scalability and I believe it's more secured than PoS algorithm, also algorithm isn't what determines the future of any projects, there are 100s of coins that are running on PoS algorithm even before ETH and they make no big difference anyways, to me ETH works better with PoW algorithm and if PoS algorithm is a must both PoW/PoS algorithm should be available on ETH chain
