Decentralization is necessary, but is it possible? I can't truly tell, as centralization is formed through power of the few individuals that make all the decisions. I maybe act as an utopian, but harsh reality strikes me every time I look at the cryptocurrencies. Something that is made to be a breakthrough in the world economics uses the so proclaimed economical dogmas that brought us here in the first place. (centralized banking system for starters) It started as a great idea (like most of the old systems did) but execution is not proving to be so great. We are just to hope that this isn't another pump and dump scheme, because the only ones that are going to profit from it are the pumpers themselves. Have a nice day!
