Of course! I am afraid of hackers hacking my coins or account, who isn't? Just the mere thinking that someone is trying to steal something from you is alarming and must be prevented. That's why you should secure yourself from the hackers, that is your responsibility. For those site who where hacked it should be the sites developers / Owners should be held responsible. But most reported sites that were hacked I am quite skeptical on those sites, it could be they just declared they were hacked so they can run with your coins stored at their sites, that is a big possibility.
