Try Quests to earn crypto3. Transaction Fees
Here I use terra.swaps to compare the total daily fees for each terra stablecoin. It is clear to see that UST produces the largest amount of transaction fees. There is a large spike of fees paid on June 17th for UST, but not for the other stablecoins. If we take away UST (see the 2nd chart below) you can see that the fees paid is a lot closer between the stablecoins. The top 3 after UST seem to be KRT, MNT and SDT - with the remaining stablecoins looking to be fairly negligible in comparison.
