If everyone agrees on something from the begining how can it be a scam?
They do not garnatee you any returns unlike ponzi which claim the world to you.
1) OGNasty and Pirate agreed in advance to lose 99% of coins in their pass through ponzi. Do you think that was a scam, or do you
not care?
2) For the second time - ponzis promise
unsustainable returns, not
guaranteed returns. If the US government issues a Covid bond with a guaranteed return of 2.5%, it's not a ponzi.
