Stellar also supports the creation of stablecoins [1], which tend to have a consistent price relative to some other asset (Often USD).

The way stellar works is pretty smart, if I have some currency on the stellar network and you only accept some other currency, it automatically looks for people willing to exchange them to find you a good rate. So even if few people use your favorite stablecoin you can still accept payments in it.
