The current circulating supply of DAI is slightly above 6B, so what you claimed is literally impossible.

The average case scenario is some of it is ponzi mixed in with other non ponzi, and in my book I'll call even a "10% ponzi", a ponzi scheme. Maybe you have a different bar to calling something a ponzi, so knock yourself out.

Loans are money. Collaterals can be "minted DAI", whatever it is, or anything else that a fool can be convinced is valuable: that is the opportunity for Ponzi schemes.

Please explain further what this means and how it helps.
