Hasn't this kind of bad news for stablecoins been around for a long time? but what effect? in fact it is still the top choice for stablecoins, but indeed when there is a problem with a stablecoin especially USDT it will affect the market, and I'm sure it will affect other crypto assets.
For other alternatives there are still USDC and BUSD for a stablecoin.
It is true that doubts about USDT have existed for a very long time and this has not affected the price at all, however there is no guarantee this is going to keep being the case, we know that markets move on emotions and if fear were to overtake those that are holding stable coins like USDT right now then I have no doubts that a significant decrease in its price could be possible, and if that happens most likely it would be impossible for you to escape such movement unharmed as you were not expecting it.
