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.
FUD alert, the haters are here again to talk shit about bitcoin and how we are not going to see a growth in the price of the coin, well I think this is very familiar and what have always been the end of it, lies. We have seen people who have influence in the world calling bitcoin a scam and yet we still saw a significant growth in the price of bitcoin so you should watch your statement and better go get some bitcoin in your wallet because the bull run is here.
