We shouldn't be using these sites if PND wants the title of "antiscam coin"
(Note: I'm not calling this site a scam and it looks like it works as described but is still a ponzi)
It's clearly a ponzi (pndPONZI.org) and people with the most basic of common sense should know better than to play a ponzi. Those using the sites should know what they're getting into.
Just don't come running and crying about how "pndPONZI.org ate my money" or "Wahh wahhh waiting time is too long". We're definitely anti-scam coin but if people are willingly and KNOWINGLY participate in a fraudulent investment operation, it's wholly their own fault if they lose money. (if you win, grats!)
