I do understand this idea. People create the values because without them there will be no demands and so the price should go down. It is the basic law of demand and supply. But honestly I also wanted to know why there was a news about price manipulation several months ago? Is it because there are people who are really setting the price such that exchanges only follows them or perhaps add a bit of increase or decrease on the prices? Or do Exchanges set their own value without even trying to consider other prices as well? And who sets miner fees? Aren't they the same person or group of people? These things aren't really so clear to me yet they are so important in undestanding the whole process in my own opinion. Any help is greatly appreciated. Thanks!
