Just like what most people would say, why would sell it if you can make money out of it and for a ridiculously 15 BTC, you won't find a buyer for that. Out of curiosity,  I checked the link you've posted download the PDF and check the link to actual trovo live but it doesn't show anything (or was it only available when you are doing it live). Also, I checked the PDF that says "This contains confidential information" but there's no actual info and just pure BS.

And the last part was pretty solid too.
"NO DEMO. NO TRIAL. NO CLONE. NO ESCROW."
"YOU ARE EITHER THE ONE BUYER...OR PART OF THE NOISE."

Seriously? You think anyone could fall to this petty attempt?
