My pet conspiracy theory: cryptodouble to pump BTC
So far, people are only sending petty money.
A hypothesis is that: what they want is for people to not only invest more money, but end up being so euphoric they also invest cash to buy more bitcoin (and double them), thus skyrocketing the price of Bitcoin, which is rather low at the moment. Kind of "anniversay pump" - last BTC pump was a bit more than one year ago.
And
then, they would strike.
I have no idea how plausible this is but at least if this is their idea, that would be less boring than a mere ponzi.
Because frankly, who cares for alt (except Monero, of course

)? BTC is the real deal.
Update: I've been asked "Then why are they accepting altcoins too? They want to pump every cryptocurrency?".
My answer is:
"To build trust. People in the alt scene have less money, so they can start from lower, which means they can last longer and thus grow more confidence."
