That doesn't make it a Ponzi. I get it, the company is going through some shit and things look terrible. I could care less which way it goes. But the company does/did sell hardware and makes money in other areas that arent Zencloud and Paycoin. It seems every new scam is a Ponzi and the word is used out of context very often here
Fractional reserve mining companies are ponzi's by definition. They have to take a percentage of their new clients contracts to pay out their old clients to stay afloat. Paycoin is one tool to keep the ponzi afloat while other cloud mining companies popped. Paycoin isn't a ponzi in itself , but the company who controls it likely runs a ponzi operation.
