So far i've been only loosing, so giving a try at 1BTC would not kill me !
I did not go to the site, however (you knew it was coming) if it does payoff then that doesn't mean it's not a Ponzi.
That is how a Ponzi works. They pay off until they can't.
The thing is that there will be a point when it does't pay off. That is when people get burned.
As you stated, 1BTC would not kill you (it would me since I don't have that much). So you put in the BTC and get a return. Great!!!
Then you may say (many people will), "Hey, that worked!! Let's try it again." It pays off again. You tell family and friends and before you know it, you have more BTCs into this. Before you know, it comes crashing down. Now you are sad.
How long will it take before it goes down. No one can say. It can be days, weeks, or years.
It took about 10 years*
before Bernard Madoff's**
Ponzi can to light. I'm not saying that people did not know this was a scam before that. People just didn't believe (or want to believe).
Harry M. Markopolos published a book about this called, No One Would Listen: A True Financial Thriller
Will I be able to write No One Would Listen 2, if that scheme takes off? I wonder if I'll get paid in BitCoins when this happens? *
I use 10 years because that how long it took for the U.S. Government started to believe. This was after Harry M. Markopolos went to the U.S. Securities and Exchange Commission (SEC) with proof (Look SEC, the numbers do not match). Now the U.S. thinks this was going on since the 1970s.

for more details.**
Madoff pleaded guilty in March 2009 for his Ponzi. That was a good run.
