Always be sceptical about new and unknown services/websites, even if they might be legit. If you are looking for trading across currencies and fiat, I warmly suggest Binance or similar known exchanges. On Binance you can buy sell and trade really quick and it has a simple system you can use.

It's always better to use such known and popular platforms which actually guarantee some safety to users.

And as commented already, the domain is for sale. Shady business.
