If the bitcoin is legalised as a currency in Japan. It will affect the decisioin in other countries. So it is good.
Anyone who wants to wait for government recognition/permission clearly doesn't understand what Bitcoin is all about. All private currencies in recent years have been targeted, by governments, as counterfeiting operations.
Bitcoin changed that forever. And no-one asked permission, or for recognition. And now, governments are beginning to say "oh, you Bitcoin people need recognition from us, that's what you need". Funny how they've come crawling now that they realise it can't be stopped.
Bitcoin was heavily discredited by governments, financial "experts" and central banks for the first 5-6 years of it's life, and now they want to acknowledge it? As a Bitcoiner, I do not recognise or acknowledge the Japanese government (or any other) whatsoever.
