Can you share a link to which coin you are referring to?
Stablecoins are supposed to be backed up by the original currency which they represent but I don’t know how authentic their verification is if they are truly backed up or not, but one thing about them is that the value only happens to climb down each time that the coins experience some crash and it depegged I don’t know if I have ever seen any stable coins which they run sales for which the price is below what it’s suppose to be.
