Hmm, I just checked coinmarketcap now, and theres no KRW. Can you give me the link? Anyway if this is true , the Korean coin KRW must be centralized and controlled by their government? Can we mixed a centralized with decentralized coin like BTC, ETH?
won is the literally the currency (fiat) of south korea, like how the dollar is the currency of the us, and the pound for the UK. you could at least do a simple google search and not look like a total idiot. During the past 2-3 months, there has been a spike in demand from both Japan and South Korea. The spike in Japan was caused by the legalization of Bitcoin there. But IMO, the sudden surge in South Korea was caused by the tensions with the DPRK. The southerners are worried that their currency may get devalued. So they are moving their wealth to some safe asset.
it's not just the north / south tensions that are causing this, sure it may have been a contributing factor, but even then no sane person would convert their entire liquidity into a single asset (bitcoin). the south korean government has been passing legislature that favors the growth and use of bitcoin in recent times, apparently there was another piece of legislation passed that made the seizure of bitcoin unlawful, just one off the top of my head. As for japan, they seem to wholeheartedly be on board with bitcoin, with that large company pouring millions into a mining farm with 7nm technology and the central government legalizing bitcoin some time ago. seems to me the future of bitcoin will start with the help of these two countries.
