Stable coins have actually misled many people, especially, those algorithmic stable coins that are called  stable coins but they are actually not stable coins because many if them in the past have caused significant loss to investors as the coin thought to be pegged with fiat reduce in price. The last example with such significant loss is UST.

Not only that, also that many of them are centralized, to the extent some can even be freezed on noncustododial wallet. Then why people going for this option when not having full control just like while using fiat. Fiat is far better to be used for holding than stable coins if not holding for long, because if holding for long, fiat will depreciate in price while bitcoin will appreciate.
