Oh no, Japan law recognising Bitcoin as legal tender, Swiss public transport and municipal tax payable in Bitcoin, universities accepting Bitcoin as fee payments, hell, regulated and licenced merchants accepting all my bitcoin all these years... Fake news? Where have you been OP?
Bitcoin penetration in Japan is very good. As we know that Japan has been trapped in a downward spiral of deflation for decades, this has made the economy in Japan less excited. Japan decided to adopt bitcoin as an alternative to facing Japan's economic problems, because of the benefits it received from bitcoin trading, spurring people's income and in the end, it could strengthen the desire for consumption which would boost Japan's GDP.
In addition, Japan took the momentum when major countries in Asia rejected bitcoin, so that many bitcoin investments entered Japan, as evidenced by bitcoin trading with Yen, the second largest in the world. The main target for the adoption of bitcoin in Japan as a legal tender is to change the consumption pattern of the people from like to save to like to invest and spend, which in the end could be a solution for deflation in Japan.
