I read this morning a blog that says that the market exchange in korea has been hacked, following the news:
https://www.bloomberg.com/amp/news/articles/2018-06-10/bitcoin-tumbles-...-change-hackI do not really know this news is true or just a hoax, but some parties justify the information, mentioned that in this week altcoin has decreased by 42 billion USD and it refers to South Korean market exchange that is Coinrail is hacked by irresponsible parties.
After at januari exchange Japan that is Coincheck is hacked now Korean exchange. It's like triggering traders' fears of an Exchange's security system, and they do not want to lose more and maybe because of it too, the Bitcoin and Altcoin prices are currently down.
Can Bitcoin and Altcoin recover in the near future? Because I believe that this impact will invite a lot of public sentiment about the level of crypto currency security in the eyes of all traders around the world.
