I think this is very good news I can ever heard that two very large and developed countries has decided to be a part of bitcoin family, though their mode of involvement is different but in the end they are promoting bitcoin by their actions and this is all we want I guess. USA is selling seized bitcoins money and converting it back to usd , this will help in hiking the valuation of bitcoin while on the other hand japan has decided to pay salaries to their employees in the form of bitcoin, I think the era of bitcoin has started.
