There're two side to this story one we all should get happy and say there're no regulation but wait what about the existing one's. Secondly does G20 really have any sizeable say in the global economy, I don't think so. When was the last time you saw them do something and all nations adapt to it. We should take this news with a pinch of salt, as there's nothing great if one deeply analysis this. Well for the sake of Bitcoins I do hope no more regulation come up.
