To make clear the mechanics of such pyramid.
No doubt in creators price grow.
The only concern is a new users - if they are - there is a market with supply and demand.
System itself has no dead end - price can rise 3 - 6 - even 12 months.
So its really nice idea, if user believe's in growth he will BUY at any time.
But to make profit he must invite referrals - his future profits are made from there funds.
Win-win strategy here is buy at current price, immediately make a sell order (+30% / +50% depends how greedy you are

)
and start lookin for someone who could buy you offer after a week or so.
