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.
No, I guess rather than demotivating the people around bitcoin community, we should add hype to the bitcoins latest market price. That will going to work as people keeps on investing, market price is getting even better. Bitcoin community is so huge it can even pass 10K dollars this year.
