A simple google was enough and i already told you that maybe you are not aware of it or have not done anything shady in the run but sadly it is acting in such a way. The difference is of the operator and the profits are taken instead of being given.
A Ponzi scheme is a fraudulent investment operation where the operator, an individual or organization, pays returns to its investors from new capital paid to the operators by new investors, rather than from profit earned by the operator.
By your definition, that would make Bitcoin itself a ponzi scheme. GTFO.
anyways,I am sure that you havent read anything but i don't know what stops me to cashout my bitcoins whenever i want ? do i have to wait for new investors ? NO i don't need to and thus bitcoin is not a ponzi.
I have clearly stated above that the developer might not be involved but there are a couple of people who are present to play the role,which requires new one's to continue the cycle .
When you cash out those bitcoin, where do you think the fiat is coming from? You don't think the Bitcoin economy relies at all on getting new investors from time to time? OK, whatever.
it doesn't relies but yes it has an effect for sure. There is a big difference between the two.
