so, they are burning TRX just to get the price up, and then the big bags will dump on the market?

Nope. They just started doing the same thing as Luna so they are printing USDD. But USDD MC is only 600M and TRX MC is over 7.5B. So USDD for now is overcollateralized. Once USDD gets over TRX in a significant way, as soon as a small bankrun starts, death spiral... But it's gonna take a while. People need to forget Luna ust crash, get a narrative that USDD is safe because of some different concept that you can make money out of thin air????. Then it will be the time for shorting
