"I'm not sure I would personally call steemit a "ponzi-scheme""

A "ponzi scheme" is any scheme in which you invest money, and by its design, essentially provides no chance of ever making a return on that money, despite claims to the contrary. Steemit claims you can make money by curating posts, whereas in reality, the vast majority of Steemit members can not and will not do so.

"(nobody promised you'd double or triple your money in a short span of time)."

While it's true that nobody promised that you can double or triple your money, Steemit does claim that you can make money by curating other authors' posts. In reality however, that is simply not the case for most members. Steemit does not state anywhere that the chances of making any money at all, is fully dependent upon both making a significant investment, and on having a relatively high reputation rate. Those 2 facts will immediately eliminate the vast majority of Steemit members. Only a very small number will invest the amount necessary (if any), and gaining a high reputation is next to impossible when you have so many unethical members who are constantly downvoting members with lower reputations than themselves, for no reason at all in the vast majority of cases.
