My personal belief is that PoW assets need to go away, and fast. That being said, the top five assets (based on market cap) are all PoW - most laymen (read: statespersons) are probably only aware of the top two, and Dogecoin.
That's because "pure" PoS is a pipe dream. For PoS to work the network needs to start with PoW or a pre-sale (ETH did both). Staking 0 value tokens doesn't work. PoW is the most efficient method to convert raw energy to a digital and secure token. The value off all BTC in existence === all energy spent since the genesis block
1) BTC - PoW 2) ETH - PoW (but the Beacon chain PoS merge seems to be going well) 3) BNB - PoS-like 4) XRP - PoS 5) SOL - PoS
So of the top five really only BTC & ETH are PoW and soon it will just be BTC.
All PoW miners are rational actors that choose to spend energy to secure the network. We can and should push that the energy is generated cleanly and renewably, thus pushing clean energy further as there is a clear incentive for use, regardless of external load or demand.
