What is the purpose of holding stable coin like USDT mate ? You can buy USDT and start trading with it to gain profit.
But you won't get anything from holding USDT in your wallet. Less volatile coin is not a stable coin.
Im usually using stable coin such USDT as my base trading pair on exchange.
There's no profit in stable coins. Some traders are using it to cut loss if the price is declining, then buying back once the market turns better.
We need to take risk in order to gain its part of investing. Bitcoin and other altcoins are high volatile and risky but its much better because of getting more profit.
