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.
So what is your prediction now when the price is above five thousand dollars, it is just manipulated by day traders

, this is the first time i am hearing this, why not they manipulate the price o a daily basis and make a hell lot of money, just doing at for a few occasions just kills the fun right

In your concept which is the most decentralized coin and most secure. If you start a topic and claim some stupid things about bitcoin is not secure, you have to explain that clearly so that everyone can understand.
