1. Users should know how to determine who are the legit admin in Telegram group. You can identify that by seeing an admin tag across the Telegram name. If someone claims that he/she is an admin or support, but doesn't have the admin tag, you should not deal with him. Ask an admin first to verify.
2. When you check all the members of the group, the admin has a star beside his name too:
3. If anyone in telegram asked you to send him money/cryptocurrency or go to a site that needs your log in credentials/private key/phrase/keystore file, he shouldn't be trusted. Even an admin won't do that.
4. When you visit a site, always check and verify the URL first before anything else.
Information about phishing sites can be seen here and there online. The problem is that, some people tend to trust easily and not verify the user they are dealing with and the website they visit.
