Too bad for those who lost their bitcoins when korean exchange was ransacked, that's why experienced users stronly advices newbies to not store cryptocurrencies on exchanges even if it is convenient. My thought here is that the dump we are seeing now is merely a correction, so I wouldn't call it a drop because IMO btc is a little overpriced before the drop. Now, I am seeing a healthier market despite it being priced at 7403$ according to coinmarketcap.
