Hmm, this looks a bit suspicious. 13 btc is a lot but about the right amount for a small hospital fee or something.
You have got to be friggin kidding me. Stealing is STEALING. You can't justify it.
If you want to do a Ponzi site then do one. But do it properly. Either code a site or hire someone etc., then put your reputation and honest effort into it. Stop trying to make a bad scam something nicer than it is. Have some respect for those who lost money.
