usual es la cadena, la stablecoin es usdo ya en coinmarketcap

$USUAL I have a question if someone is kind enough to explain to me, in the usual descriptions it says that it is a stablecoin that will be equivalent to the dollar. If this is the case, how is it possible that many say it will be worth 2 dollars? It should be worth the same as 1 dollar, right?
