At this moment, more than 3700 users around the world, who entered data into smart-contract more than 7600 Ether !!!
I think, that is:
1. Project "333 ETH" is not a "Ponzi Sheme", because there is no person, no a company (businessman), who
"pays profits to earlier investors using funds obtained from newer investors"...
It's smart-contract algorithm (program code) on which the project is based is uploaded to the blockchain Ethereum 03.09.18 with the OWNERSHIP WAIVER function ("REFUSAL of OWNERSHIP"). This means that nobody - including the organizers- can access it to tamper with its independent functioning.
2. Admins does not have access to the main purse of the contract, it does not have the opportunity to withdraw funds from the smart-contract. Admins does not engage in the rescheduling of the ether* among the participants - it's function of the independent smart-contract.
3. Project "333 ETH" isn't working with world currency of exchange (like USD or Euro), smart-contract "333 ETH" is distribution of Ether* between participants (ether can be transferred between accounts and used to compensate participant mining nodes for computations performed).
4. Developers of 333eth[dot]io 14.09. opened his source-code of smart contract for analising by each one!
