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.
