I personally don't trust in stablecoin (including USDT), because stablecoin also have risks (the price can crash like UST) and of course that can also happen to USDT (although the probability is very small), but still USDT have risks, therefore I never use stablecoin and always save my money in Bitcoin, because Bitcoin and stablecoin both have risks, but at least Bitcoin can give me profit and stablecoin can't give me profit.
well there's certainly some edge where you will definitely need to make some preservation in your wealth and that's when stablecoin come in handy, even though you don't trust stablecoin in general.
just using it temporarily for preserving the value of your investment will only bring benefits and eliminate disadvantages.
after all you only gonna convert it again at the end of the day, it only become a mess only if you decide to just keep your USDT for a whole year or more then there's risk that something obscure might be happening to your investment.
but generally if it's only for temporary means of saving wealth from the volatility, it's gonna be fine.
