Then Bitcoin has a lot of work to do
Discussion
There are a lot of variables contributing to the decline of birth rate in South Korea, but core to them is the inflation of the WON. But as South Koreans at all levels of society adapt Bitcoin, the decline in birth rate will reverse along with many anti-marriage, anti-family, and anti-children policies. One of the Dynamics of Korean culture is that once something catches on everyone begins doing it extremely quickly, and the same will go for Bitcoin. A brighter day is coming for South Korea.
To every complex problem there's a simple, and wrong, answer
There is nothing simple about Bitcoin applied as a store of value, medium of exchange, and unit of account within household finances, let alone on a city, nation state, and corporation echelons in South Korea and worldwide. But because money is upstream from culture, media, family, government and laws, and language, etc., it is a cornerstone of the world that when broken, leads to many problems, and when fixed, solves many problems. But if you've given insufficient extrapolative thought to what using sound money actually means, to the outcomes it actually leads to, you would already understand it's a complex fix for complex problems.
Bitcoin is great, but it's not a panacea for every problem facing modern man
