You are wrong. Monero is not a ponzi scheme. Pyramid scheme it indeed is but not a ponzi.
If you call Monero ponzi you also need to call gold bullion ponzi scheme. In general anything that has value need to have some sort of constraints in the supply side. Monero has an algorithm that sets tight limits on how much coins will be mined in x period.
I am telling you guys, there are only around 5 million Moneros to be mined before the tail emission starts to kick into the game and then it is game over day for the shorters.

Monero needs to have fresh hands that takes your coins which you probably bought higher and are now complaining here.
If you feel like you want to sell more coins, please do so. You can even borrow some Moneros which I will among the other people here buying and lending back to you. Bear in mind, the lenders are the kings in the markets because they can stop lending and withdrawing their coins at any minute.
