The authenticity of a cryptocurrency exchange can normally be known by verifying the authenticity of the license for operation of the cryptocurrency exchange from the regulatory authority from which it has obtained the license.

This also highlights the fact that unlicensed cryptocurrency exchanges or exchanges which claim to have licenses from unverified sources should be avoided as a rule of thumb.

The users must also verify the regulations which were followed at the time of providing a license to the exchange. This would help the users to know if the exchanges had to comply with adequate standards to obtain the license.
