Each country has its own regulations. If it were up to them to use a currency, regardless of inflation, those countries wouldn't use any other currency. In our own country (Indonesia), crypto is considered an asset, be it Bitcoin (BTC) or altcoins, it can't be used as payment method. So, specifically for our country, $USDT, $USDC & other stablecoins will only be used for trading purposes on CEX, it will never be a daily use.
