Maybe a silly question, but if the concept of a stable coin is to maintain market cap (i.e. coin price) by dynamically altering the supply and/or demand. (e.g. Tether, Ampleforth) then what is the potential for a return on investment? For example, if USDT is always about $1 what's the upside of investing in it if the price never goes up?
To be honest there is no return of invest from investing on a stable coin like USDT.
ROI comes from the price changes of something has stable value then its not an investment.
