Wow, that is some big amount for most of people, i can life a happy live a happy life if i have that.
Sorry bout that, but i am sorry for your loss, i hope you can get more bitcoin later in a short time. I cant even imagine if i ever lose up to 0.1 bitcoin, and you lose up to that amount, iy must be really really bad experience for you.
This could be a lesson for you, and for all of us, to be more careful using a computer, and for the best, use a hardware wallet for bitcoin.
