I'm from Venezuela, and I can tell you that here there are many people adopting 100% cryptocurrencies, I am one, I have 99% of my capital in cryptocurrencies, some say I'm crazy for doing something like that, but I really have more confidence in the cryptocurrencies than in the national currency.
For two years I have been investing in cryptocurrencies, at first it was just Bitcoin, then others came, later, last year, I discovered Steemit, and I joined the platform, I was surprised to find many Venezuelans here, and not only that, but also they use Steemit as a MAIN source of income.
I imagine that in Korea things are different.
