I can never understand why people create stablecoins, which are already a lot? Or is one better than the other?
Because stablecoin is widely used to store the value of your investment, there is an advantage for an exchange for having its own stablecoin because it can be used as a tool to store user assets value in their platform and getting attraction from the people. By having their own stablecoin, it can boost traders faith in using their platform because they have a way to store their investment value.
