It is estimated that TFL's wallets hold more than 2 billion $USTC. The total supply of $USTC is 6 billion. TFL holds more than a third of this supply.
TFL's burns of $LUNC and $USTC will take place soon. As part of the agreement between TFL and the SEC, TFL is required to burn all of its Terra and Terra Classic assets... $LUNA has been burned. Next are $LUNC and $USTC.
With the TFL burns, it is expected that the supply of $USTC will decrease by a third, falling below 4 billion.
