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? 
We both are on the same page. We have been hearing this news from quite some time. It is true that bitcoin and altcoin's value in Korean exchanges are really higher than any other exchange, almost 30% higher. So the risk of money laundering is way higher in the Korean exchanges compared to any other exchange. However, the Korean government has not yet come up with any concrete notification about this ban. It is speculated that Korean government will ban bitcoin and altcoin exchange like bithumb or Kraken, but no one knows for sure.
