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.
Oh Ok, I misread the OP's opening post completely. My apologies to the OP for commenting and not reading throughly his opening post. It sucks to lose so much money. I hope you will manage to recover somehow and that you will stay with us, as a part of Bitcoin community.
Good luck!
