Since before you write your post you could not fully understand the rules of Ponzi where it is directly written that they refuse to own a smart contract and as a result can not escape with the money of depositors
Actually all people can lose money. Lets say there are only 2 depositors(lets call them D1 and D2) and 0% fee:
D1) invest 1$
D2) invest 1$
D1) receive 2$
D1) reinvest 2$
D2) receive 2$
D2) reinvest 2$
Both depositors are now waiting for 4$ while there is only 2$ in the "game".
See? Everyone loses, fee is irrelevant.
To my regret, you are not right, dear marlboroza. One of these two investors takes the entire bank. That is, he will take 2 dollars and will receive a profit of 100%. The second will lose. If you do me a favor and get acquainted with the project, then I will not have to explain simple things.
