Not sure if its been posted here, but I think its a big step for the coin. Hopefully they dont break the coin into unlimited and core, and other countries follow suit soon.
One reason why Japan has been among the first country to legalize btc could be because there aren't too many DNM sales going on there. But still a huge step for the coin
Must be the reason why there was a sharp spike in value
