Hackers are everywhere man. ive lost a lot of coins from exchange sites that have been hacked. There must be a solution to this type of behaviour. BTC will not grow if there isnt any trust or 100% security is implemented on sites that are holding bitcoins. I know its not easy as i say but more should be invested in keeping the currency safe and have measures to prevent hackers.
It's called 2 factor authentication.
Something you know = password
Something you have = your mobile phone / crypto card / (bio info too, finger print, eyeball, face, but I'm not down with that shit!)
I lost BTC in a known exchange site even though i had 2 factor authentication. They did not require just my account, they fucked over the whole exchange site, which the 2factor cannot prevent!
