If more country's will be following the path like what Japan did, I think it would possibly will take effect on the price to become more valuable in the future coming months. More nations adopting bitcoin has a good effect of bitcoin community, because demand will also follow as it will be more sufficient to reach that higher price value, and hopefully china and other developed countries will also accept bitcoin as one of their reliable currency of the country.
This is impossible. China currently imposes stringent economic controls. Their government strictly prohibits the outflow of funds. They will not allow the existence of bitcoin at all because they believe that the existence of bitcoin will weaken their control over the economy. At present, only Bitcoins are strongly repelled. Although it is difficult for them to effectively control bitcoins, they have caused many people to panic because they issued a ban on Bitcoin. This is what happened on September 4 last year. We should be clear. I think that it will be difficult for China to embrace bitcoin again in the future.
