However if there really was a situation like this, it was undeniable, it would definitely be difficult. If a stable coin that is trusted enough and is used by many people and various exchanges, and suddenly drops or has a rug pull, then there will be some problems. especially if the coin cannot be sold or converted again to other coins. This is going to be a big deal. Maybe this will be difficult to happen but that doesn't mean it's impossible. Because it could happen in the future due to something really bad.
That's why I personally don't think about keeping assets in USDT or stable coins, only using them sometimes for pairs in trading. However, we must always be vigilant and always update the market and news to quickly avoid unwanted things.
