I wouldn't want to even speculate at the methods they would use to find out who you are...and extract the keys from your sorry ass.
I would be very very afraid if I was the one who hacked those coins...there is no place on earth safe enough to protect someone who stole that amount of money from the USG.
If it was me, and I was some how able to do it, I would go straight onto this forum and get everyones addresses and start sending everyone an even share lol that would be amazing
The only bad thing is the NSA has so many accounts on here they would get most of their coins back.
