Pincus is no Jobs. He "pumped and dumped" Zynga, he'll be out of Zynga in less than a year. But I'm sure he'll make a lot of money off Zynga in the mean time ,like he did before.
Unfortunately it looks like longbets have to be at least 2 years. I routinely make wagers like this and always pay up if I lose (though my opponents sometimes welch). I'm super easy to find on the internet.
