One look at their site is enough for me to know that it is an amateur or scam exchange. No serious service provider would allow themselves to have such an amateurishly made website, full of grammatical errors.
My friend had already deposited some usdt in the website and although it looks like an exchange platform but something fishing I assume is up with the site.
Best to stay away from that exchange. If they can't even bother to present a professional and error-free website, it's a major red flag. And tell your friend that the next time he asks, he should consult you before depositing his funds, because, from the looks of it, it is highly unlikely that he will ever get his money back.
