South Korea is preparing to tax bitcoin use after the cryptocurrencys trading volume skyrocketed past that of Kosdaq.
Death and taxes ... it seems that even bitcoins can't escape that

I don't really know how koreans will ever do this but the way I see it, the government will be taxing their money from bitcoins the moment they cash out. I don't know why but it seems to me that the SK government is just trying to fishout some money out of bitcoin transactions in their country.
