How did this guy steel the ETH from you if I may ask?
And about your bounty I don't think anyone will track the theif for 100 bucks. Because first it's very hard to track someone in the blockchain and second even if someone was able to brute force that wallet for you you probably won't find anything in there cause the thief has already spent the money!btw (how much money we are talking about here? )
Enough to annoy me, and I bet he hacked the private key somehow. But it isn't really about the money, as far as I'm concerned, other than the fact that I have a few investments and some stuff from bounty campaigns that I had plans for. I can bump up the bounty if I have to, and when I get a few payments I'm expecting. The important thing to me is getting that guy shut down.
