What is the purpose of buying USDT?

Hello there, I'm curious about the reasons behind purchasing USDT. Could you elaborate on the purpose of acquiring this cryptocurrency? I've heard it's widely used in the finance world, but I'm still a bit hazy on its exact benefits. Is it primarily for trading, storing value, or perhaps for some other strategic reasons? Could you provide some insights into the various motivations that might drive someone to invest in USDT? I'm eager to understand its role in the larger cryptocurrency and financial ecosystem.
