I don't think other countries will adopt what's with japan right now, and its really hard going into cryptocurrency if each country government will not be accept it. Good thing about with Japan's government was united with this adoption, and the people itself were having deepest trust with bitcoin. Their place was merged into the fiat system especially the economic trend of the country weren't able to neglect the fact that bitcoin was volatile. Despite of that, the people in their country learned a good attitude by holding bitcoin for a purpose of long term investments and not a day trading scenario. If they sell their assets, they don't sell those that they don't need but instead dumping btc depends on how they really need it for their immediate expenses.
