It is legal man. Legal..

Fairly sure it isn't
As seen in stock exchange markets. You sell it cheap and some one takes your money that you bought some time ago at high

Deposits will not work some time.
Because admin ; he/she wants to be the ONLY buyer at Khs market..
He wants to buy his/her Khs back.

So not ponzi? MARCELO pays you for pretend hashs I am confsued
He/she sold you Khs prices @900 right ?
Now he/se will buys them back at may be @100 right ?
No buy wall because no deposit. Admin is the only big buyer.
So it is not ponzi, it is a well planned stock market tactic.
It is used by cavemans also; to kill bisons, panic them and kill them with mass, drop from high clifs.
