Currently there are some news report about korean government. The report say the government there has great concern on bitcoin. Bitcoin has been very popular in korean. What we saw is that the price of altcoin is much higher in korean than the average around the world. However, the unconfirmed message about government's decision now gave a bit hit on bitcoin price. What we saw these two days is the continuous decreasing of all in the market. What if korean really close up exchange? It may pull the price down to zero!!!! I guese. So, do you think whether korean would shut down bitcoin exchange? Would that also lead other governments(like US or China) to close exchange? what if all exchanges are closed up in the world? 
The Korean government's financial watchdog also said it was considering expanding current trade regulations to include virtual currency. However, this extension should also have a legal basis. These regulations include confirmation of the identity of investors, declaration of operating income, supply of electronic wallet codes for money laundering prevention and control. The introduction of more regulations will help the virtual currency market in the country reduce the fraud. South Korea, despite being known as one of the world's largest virtual currency trading countries, is suffering a lot from investors here.
