So if you can tell more about it OP if you've seen some other domains then tell it here so that if it's not an official one, it's likely a phishing site that copies binance. As it will serve as a warning to the others and to yourself too.
There is an important and very useful tool for Binance users' security called Binance Verify. Through this tool, you can input a URL, email address, any social media accounts, phone numbers, or Telegram accounts to check if they have been verified by Binance and are official or not.
Therefore, if the source I entered is an official website from Binance, it will undoubtedly be safe to use. However, if the source is not an official/unverified website, it will undoubtedly be unsafe and potentially a phishing site, so it should not be trusted at all.
