Be wary of a price that is too low and too attractive. Usually, fake assets built on platforms will have a very low price. If it is an ICO token, always confirm on the official page for the usual token compensation for your Bitcoin or Ethereum.
Another way to know a real asset from a fake one is to check the asset ID. Verification can be done via asset ID & not name.
Plus, check the receiving wallet. Look out for negative comments or users demanding their money back. Remember that sending Ethereum is irreversible, and after you receive a token that is not traded anywhere, you are stuck with this zero-value asset.
