From all the major flaws presented in Bitcoin one could say PoW is the major flaw of them all making the coin more centralized than even most people can't afford to keep up with other miners, these are day traders doing there thing again making profits on your losses, beware most say it's like gold it doesn't need to be fast but in reality it just isn't so secure.
I don't think people would care that much at all as long as it's a sound money. As long as you can take profit money from it, just ride with it. Bitcoin croased 5'000$ just a week ago and I think it's a good step the current market had taken so far.
