My pet conspiracy theory: cryptodouble to pump BTC
So far, people are only sending petty money.
A hypothesis is that what they want it to people not only to invest more money, but to invest that much money that people will start buying bitcoin with fiat, 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 they, they will 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? BTC is the real deal.
That's quite interesting - and very plausible
