I've got a question: Why?
Why has Japan decided to legalize bitcoin now? I've heard about "it's is good for innovation", "the will to lead the bitcoin economy" etc... but this seems to me quite peculiar for a government not very renowned for its audacious moves (the quantitative easing as everybody, the explosion of the debt etc...).
Or maybe they are in so dire straits, the Yen is about to flank in about a moment, they know they will default soon etc... Something seems fishy here.
