A great news indeed. Based on what I read on the article above, In an estimate, "South Korea accounts 20 percent of the bit coin trades world wide." So it is safe to assume that this change will have a big impact on Bitcoin and its current value. I can't wait to see the Bitcoin price back up gain.
Considering that investors will accept to convert their virtual bank accounts to real-name bank accounts, although some of the main features of Bitcoin is being decentralized and pseudo-anonymous. So in their case, if they want to continue trading cryptocurrencies in their country, they have to accept these new regulations that their Government imposed. Assuming that they will, there will be a huge possibility of a price surge again for Bitcoin as per stated in the article that 20% of the Bitcoin trades worldwide are accounted in South Korea.
