There are many ways to check the exchange. Initially, you need to check if there is an exchange in the CoinMarkerCap listing. Check reviews on forums, in social networks, you can also google and read what other people who have already worked with the platform write. I do not understand people who make deposit a large amount on a new exchange, and then complain that they were deceived. Most likely, your first withdrawal of funds will be approved, this is what scammers do. But you dont get second withdrawal , they will block you and you will not even be able to write to the support. Do not trust the media, they all take money for writing reviews and articles about projects, and which project will pay money so that the media write badly about it? There are always flaws
