No, it's not sincerity.
I'm a biznessman too, and i could just tell from the way these guys were talking that they had something that's real. The words they used, the details that rolled off their tongues, the level of comfort with the concepts. They are obviously living and working this stuff everyday, and it shows.
What they have is for real, that is my very strong opinion.
I have a good eye and ear for BS, and those CCs were GREAT!!
Think about it - his honesty hurt him badly and he took it like a man. If this was a scam, he would have came on there and said, "China is coming together, and it looks like we'll be launching in the next 30-60 days, and that is going to be HUGE!!" - BUT he didn't.
Think!!! What makes the most sense?
