What aspect of FGX helps in preventing potential fraud?

The aspect of FGX that significantly assists in preventing potential fraud is the Know Your Customer (KYC) processes. KYC refers to the regulations and procedures aimed at verifying the identity of clients to ensure that they are legitimate and not involved in illegal activities such as money laundering or fraud.

Implementing robust KYC processes allows FGX to gather essential information about customers, including their identity, financial history, and the nature of their business activities. This not only establishes the customer's credibility but also enables the exchange to monitor and flag any unusual or suspicious transactions. By understanding their customers thoroughly, FGX can mitigate risks and enhance the overall security of their operations.

The other options, while beneficial to the user experience or the business model, do not directly contribute to fraud prevention. A user-friendly online platform enhances accessibility and customer satisfaction, while low transaction fees are focused on making the service economical for users. The variety of available currencies caters to customer preferences but does not address the requirements of due diligence and fraud prevention that KYC processes provide.
