ASICS are never good for distribution
Is there a proposal to change the PoW algorithm?
In my opinion, since ethereum will go PoS, ASICs will be used with other ethash coins like ethereum classic, expanse and ubiq. For sure if they produce them it's because there's demand
AFAIK, Ethereum does not support the use of ASICs. Mining goes via GPUs that consume ocean of electricity. The last sets a limit to network. PoS eliminates this.
If, you look at the top 20 crypto-currencies, 65% are not using POW.
The success with investors, of this many non-POW coins, does lead most people to conclude that Ethereum will see a good (new paradigm) valuation improvement after the POS.
