A hack in an exxhange might have been really bad. The hack might be targeted to dropping the price of some coin and making the market look bad, this will create what you call

"FUD"

This is just my own point of view. This havk was targeted on this young and low ranking exxhange cos they are the vulnerable ones and then use it to get the attention of traders in the huge market

once again FUD

Buying now is a great idea but still mind the coins you buy and the exchange you use

Thanks
