Actually this is not a problem, stablecoin does aim to have a stable value equivalent to a particular currency, so there will be many people who only aim to save their money but not in digital money in the form of a stable coin crypto, this is what making more traders choose stable coins to secure the fiat money they have without having to risk being affected by extreme price corrections such as other crypto currencies.
then they are exposing themselves to unbelievably huge risks without even knowing it!
all these so called "stable coins" are centralized and most of them are already run by shady companies that have not been able to prove they have the funds to actually back their token up in case everyone wanted to cash out to fiat.
not to mention that this is clear definition of printing money and since they are centralized government may not look kindly at them.
