What is the problem with USDT?
I've heard a lot about USDT recently, but I'm not sure what the problem is. Can you explain what's going on with it? Is it a stablecoin that's supposed to maintain a fixed value, but it's been fluctuating a lot recently? Or is there some other issue with it that I should be aware of? I'm just trying to understand what the concerns are and whether I should be worried about my investment in USDT.
