By the way, you need to know that USDT is present in different blockchain networks. I wonder if the risks are also different?
Concerning its familiarity in this space, although there is much information about regulations that have appeared to affect price stability, they still exist and are an indispensable part of the market. But in this space, it is difficult to guarantee that bad scenarios will not happen. I think the issue of choosing safe stablecoins for users on a small scale will not have too much of an impact, but on a large scale, that is a big risk sign.
It's unlikely that there are political issues behind why quality control and assessment are mentioned so much, but in my opinion, in a not yet completely decentralized environment, finding your own way out of this difficulty is difficult, and forcing stablecoins should probably also be researched. Honestly, from that point of view, I think the majority of people are more susceptible to flavor manipulation, and small-scale use is not too worrying.
