I'm not sure how much impact it will have, as crypto is already hugely popular in South Korea.

I remember this stat that over 7% of South Koreans (of those surveyed) own some crypto: https://cointelegraph.com/news/south-koreans-invest-an-average-6-000-in-cryptocurrency-says-new-survey

But even if it doesn't have much effect, whatever effect it does have will surely be positive and is another welcome step on the long and bumpy road towards the integration of crypto into mainstream society.
