Remember the blockchain is decentralized, and any project can quickly turn into a scam and disappear with the investor's money. That is much similar to EthPyramid. Most of the platform's aspects are still unknown or plain anonymous.
Additionally, the platform also works on a much similar scheme as a fraud waiting to happen. The platform intends to rely on the users inviting or referring more users for the token price and sale to go up. Such a scenario works in mostly fraudulent investment schemes, where they get many investors on board then they disappear with their money.
