Do you realize that this video doesn't contradict what I said? The hacker got caught, and (some of) the money got returned, and that's what they are showing in that video.

If the guy didn't get caught, they would have never found anything, unless the thief is dumb enough to send these coins to his exchange.

If it were me, I would randomly mix 40,000 coins between random addresses, random amounts, random times for like a year. Never using the same address again. I would mix them with other coins. You might end up with 10,000 addresses holding random amounts of coins, but that's not a big deal at all. You need some cash? LocalBitcoins in a neighboring town. Or create an online business and buy your own product from yourself. Or build a website, put ads on it, and buy quality traffic with bitcoin (arbitrage).
