Ponzi schemes don't do that to people.
GREED does that to people. And praying on your investors GREED is exactly how Ponzi schemes have and will continue to exist.
So I think the lesson in the wild west of bitcoin land is that a guy like Pirate sets up a Ponzi clearly with the intention of defrauding his investors, where as the dupped PPT's and Patrick Harnett, and Goat et al were just clueless lemmings along for the ride and then just disappear into the woodwork when the shit hits the fan.
After the Bitcoinica disaster, Amir seems to have going off the deep end. Donald Newman has all but disappeared and Patrick Strateman is still plugging away insulting his clients in the intersango thread.
Zhou Toug has taken his ill gotten gains and started nameterrific.com and is living large as he continues his education.
A guy like Roman Shtylman suffers a devastating hack (or maybe he just blew all the money on that extended london trip) and continues his busniess as he attempts to recover.
Then there is M4v3R of bitmarket.eu who decides to invest (gamble) all his client fund in bitcoinica and lost and now he's trying to recover.
All the while PREYING on their investors/clients HOPE that maybe, just maybe, by some miracle the lost fund will be recovered (yea at 0.05% of 30 years!) and they will all be made whole. And you know what. I just might put a little more money back in to help them out. Whaaaaattttttttttt!!!?
So I guess anyone in bitcoin land with little to no financial knowledge or experience and a little web design/computer skills (and a download of bootstrap) can open a bitcoin business, call themselves an "investment manager", a "exchange" a "pass through" or whatever, collect funds and then either knowingly or when things go south just close up shop claim a hack/scam/scandal and just walk away.
And so far it seem there will always be plenty of naive, clueless or just plan trusting investors/depositors to play along.
I love this place!
