the whitepaper did mention that the 30% apy will be there until the supply hit 2B mark. However we need to be flexible. making too high apy will cause public to think usdd is just like UST or unsustainable. Actually if you lock usdt-usdd lp in sunio , you can achieve 30% apy.Not sure about that because i only stake usdd in justlend.(6-20% if you know how to play around) Secondly, you raise an important question. How come TDR doesn't want to use reserve to support usdd during depeg? Hmm i think they need to save bullet. In case some speculators dump trx, they need to use that find to support TRX as well. If usdd can be pegged to 1 without much intervention of TDR, isn't that be good?Just my opnion
