I think that it will have a minor impact on cryptocurrency as a whole mainly due to the fact that it will only apply to the entertainers and their fans, although, with the large viewerbase that K-POP does have it may very well prove me wrong and absolutely take off. Additionally, most of the people who enjoy K-POP are from the younger generation and therefore are more digitally savvy, meaning that this cryptocurrency does have the ability to take off within that K-POP ecosystem, especially due to the fact that these fans are absolutely die-hard for their idols.
That may be true, however, this is most likely older men and women who are investing their income. I highly doubt that those from the younger generation have much care for their future and therefore most likely haven't invested into cryptocurrency. This could be a turning point for that, especially in South Korea.
