I just sent in my guess. It will make some of you choke on your drink.
His guess was 0.173 bet on $17.30 (you can see it in the blockexplorer link). I sent him 0.1 BTC at 1EmT2SDdKwp8Zhz3RngEHzAyBtfR5E3Usu
i bet 0.17 BTC that value will be 17$.
coming from :

According to blockexplorer, the 0.17 bet actually came from 1AMutUVeYKoePyuUNGn8dkVB7HWYCtvjKr, which is where I sent the 0.1BTC. I'm presuming it got to you alright.
And that's it for free money!
This is fun!
