Between company x announcing to accept Bitcoin and actual usage is still a world of difference. Point of sale usage of Bitcoin has been sobering so far, at least anecdotally. But who knows, if Bitcoin "clicks" with Japanese culture they may just very well improve on the point of sale process.
Agreed. I don't think that this legalization has as much effect on bitcoin and actual users of bitcoin as people think it to have. Honestly you're probably going to encouraged but probably not pushed over the edge to accept bitcoin as a merchant by the law.
But from a speculator's point of view, 8% tax is a whole lot, it means that now japanese buyers are able to have 8% more buying power than they had previously. This is obviously great news. Price of each bitcoin has risen a little, but not that much. But i think the activation of this law has brought bitcoin out of a almost week long bearish trend back into green.
