I think everyone has their own reasons for using a stable cryptocurrency,
but For example, I have a certain capital that I use to work in the cryptocurrency market, but I do not always want to keep my capital in any cryptocurrencies and therefore I choose the stablecoin USDT. And I don’t need to withdraw to a bank account or cryptocurrency all the time back and forth, and I don’t worry about fluctuations in the cryptocurrency market, since USDT is always stable.
