Thats a hot conversation and looks like lots of woos and yes, are going on here. I guess decentralisation is part of public decisions where there is no ruling body involved at all while on the other hand if any ruling body starts to control it then it can loose its balance and die eventually. Blockchain and its dependent curries bitcoin and altcoins are in the similar space where if they are supposed to be regulated then they will loose their very core properties and may not be much useful than what they are today. Its because people wont be looking at bitcoin in the similar ways as they do today. Neither there will be much investments as it would get far more centralised, and non-anonymous too. This is why I believe it has its own pros and cons.
