they did the same thing here in Colorado with Marijuana. As long as South Korea is interested in regulation and not destruction then the tax can good be a good starting point to legitimize the currency. Lets not forget that South Korea is heavily influenced by western economic power so this could be a beta test for what is to come in the US. "Hit them high and settle in the middle" works in regulations. This sucks for the average person trying to make a business out of it but that is the point of regulation. I'm not saying I'm happy about it but I could have been worse.....
