If Bitcoin would get a hold on South Korea that would be amazing.
They have quite some purchasing power over there.
Yes, it's true, I can confirm from my own experience.
I visited Seoul and S. Korea several times and it's really amazing their technical development and specially how they implement Internet, mobile phones in everyday life, communication, trade, selling etc.
So, many of them have good purchasing power and they are already using Internet in everyday activity, so if they understand and accept Bitcoin concept, it will help growth of Bitcoin.
