So you made 40 BTC in 2-3 months and suffered a 90 BTC loss due to your own stupidity. I don't think your ARG was "fun" for anyone, a 50% refund and an honest response would have been much more appropriate. Even better, an honest response and a 3-6 month compensation plan.

But yeah, since you were running a Ponzi anyway, honesty doesn't come into play. I truly hope that someone will dig up your ass in Australia or wherever it is you're holed up and make you regret this "game".
