It is the difference between offering a security/asset/investment/ponzi and promoting it.
All the promoters were lying. The "knew" Pirate could make this, they had insider "info" on that. They were willing to call those even bringing up the chance it was a ponzi every insult possible. They hyped it up, made jokes about how much the "team ponzi" was losing in profits. They staked their reps on Pirate being legit.
Pirate didn't need to give them a cut. The entire PPT system was there cut. None of them passed through 100% of the interest from Pirate. Take a PPT which paid out 4.85% on 40,000 shares. Pirate pays 7% on 40K BTC the PPT pays out 4.85%. The difference is 860 BTC per week. They had a direct profit motive to bring in as many suckers as possible.
They both promoted and profited off a ponzi through the use of deception, misleading statemented, and outright lies.
OMG something we agree on Yes brand them all
Tho people like HashKing I never saw him once promote it as a sound investment he just offered a PPT and made the risk obvious from his other deposits.
