Any news coming from Japan regarding crypto will have a effect on the ecosystem, because they are now the number one prime mover of the market. And regarding legalizing in it Japan, of course this is a very welcoming news because we all know that there's a heavy ICO crackdown ongoing around the world. And having somewhat a regulation will weed out the bad eggs specially those who are hiding behind the blanket of a project that is very promising but behind is purely garbage and the only reason that are putting it up is to scam people of their money. Let's see how it goes, because the price in the last couple of days have been spiking so maybe this is one reason.

P.S. Much better if you gave us the link so that we can see and read between the lines. Thank You.
