Damn man, that's a lot of coins and a lot of money. What I am not getting, is how this person got a hold of so many coins without knowing how to take care of them? Did some newbie just come and drop $30,000+ without knowing how to secure their investment? This is the only logical explanation.
He was taking care of them by using a paper wallet. He just pressed the wrong button at the fatal moment. I've done it plenty of times with vital things myself but thankfully there wasn't any wealth involved.
