I understand what you mean, but there could be better ways to trade with USD than with a scam token, but it is true what you say, in Argentina, for example, they use a lot of USDT to get dollars, I think stablecoins have their use, but if they continue with us it is because there is something behind it, especially knowing that they are not fully backed 1-1 with the dollar, at least Tether is known not to be.
