There is an ongoing program called Ethereum Million Money where people invest Ethereum, recruit others to invest, and they get paid from other people's investments.
It is a pyramid scheme where they use the money of new investors to pay previous investors. Just like every other HYIP, Ethereum Million Money lack the prerequisite to be sustainable for a long period.

Ethereum Million Money Is A Scam! Yes, just like Bitconnect and others which came up previously, it will still crash. It only requires a few more weeks or months before it goes down.
Anything promising you money without having any use case is a scam; except it is a charity organization.
