Where there is money there is always some tools on how to hide and launder money.
Although we all would like to see stable coins in every exchange to remove from the cryprto easy way in case of another pump. balloon. I think the main case of stable coin is to hide and launder money.
I also do not like stablecoin because I think that is what makes the market difficult to rise because currently there are many investors who store their assets at stable prices so that market growth is stalled because there are not many buying and selling transactions.
