Many still like Tether no matter issues are being thrown on it. With the volume that it has, that only tells one thing and that means that it's being trusted by many. Or not being trusted but because of the volume, they choose to use it instead of any other stable coins.
For someone like me, I have always preferred USDT. I guess it's because this was a common cryptocurrency for payment a couple of years back. And it was my favorite not knowing the things that are possible with it. I have heard that they can freeze your funds (I didn't really know this) and that is disturbing because I don't want anyone having such power over my money. Additionally, I heard that their assets aren't completely backed up, etc. Maybe the USDC is indeed a better choice. Usdc, don't ask for reasons, I just do.
This is the other one that I use these days. I don't know why as well but maybe there's a magnet on it that makes me use it because I have always seen it being said by people.
