Tether is a token that is made with a stable concept, so it is not affected by market conditions, Tether is certainly the best solution for those who are hesitant to enter the market so it is natural that currently Tether's transaction volume is the largest beating bitcoin. Of course, Tether will never drop or go up from the $1 price range.
it will never happen. because USDT is also as stable an asset as BUSD and others. they have a fairly fixed value with very little movement. its value may change when the market is in a fairly rapid trend change. like when pump and dump. we can see its value with other asset pairs has changed slightly.
