Japan has truely taken the first step in boosting its GDP and also boosting Bitcoin adoption. They've realized the potential of the technology utilized in Bitcoin and I'm glad it's been acknowledged by their Governments. I believe the few countries that have it as unregulated could be Turkey, Vietnam and probably most of the European counterparts. I am really hoping that those countries that have listed Bitcoin as illegal (Bangladesh) and possibly looking forward to limiting its use heavily (India) also try and understand the benefits it'd provide for cross-border trades and also to understand ways on legally regulating it instead of looking forward to making it illegal.
