It depends on what they do with this information, not the information itself. They really make those celebs go out and talk about crypto here and there, doesn't have to be like promotion (there is nothing to promote) but create awareness then Koreans would probably listen. Hell k-pop is global now and well beyond Korea itself only which means there are people who will literally listen all around the world.
So, those celebs talking about crypto between sentences sometimes would create a lot of awareness and they could put this over the mainstream media, that is when the real price increases start. Don't forget the more adoption we have in crypto world the more price will increase, that has always been the truth and that is what we need from these kinds of news.
