The exchanger is very easy to use, which is good, low fees, fast exchange. A letter of guarantee is also a positive point, which can eliminate all controversial issues.
Among the shortcomings, I would probably note the small number of supported networks. It would not be superfluous to have TRC20, it seems to me that USDT TRC20 is used by a much larger number of users than ERC20, for those who make frequent exchanges will pay attention to fees.
