Ill take this one....
Essentially the business model is conceptually a load of rubbish, PPT does nothing and they have no invoices to put on the system. But Mr Williams thinks that by releasing more and more types of tokens (Gold?? WTF?) it will make them sound very clever and will cause misdirection, until the bull market recommences and he can sell the remainder of his PPT tokens at a higher price (then no doubt disappear).
To most people this is clear, however to those that bought PPT high they are still clinging on to some hope.
In the end, it is the hope that kills you.
Youre welcome.
