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?
Don't use Stablecoin as a handle or hope for profit and this kind of thing, because that will be difficult. Because basically stablecoin is just a backup. Only provides convenience for crypto traders. Fee if you want to exchange another BTC / ETH or coin for USD or your country's currency will give a bigger fee, so the solution is this kind stablecoin.
But that seems true for me consider about lack of audit on stable coin that makes direct pair with fiat is much better right now. Remember about we have seen so many people have problems with stable coin.
Stable can become an alternative but it will not always become the preferred way for those who are looking for stability.
