My thoughts on decentralization: the more centralization, the more successful it is. (By that, I mean more people gathered in one place.) Not how everything is ran in the back=end. Take Hive for example, now split it up into 100 parts all with it's own thing. I don't think it would be as successful.
As for the various tokens - I have no idea why people pay for them, but I'll gladly sell them at that price. Many tokens on Hive have limited utility.
