Does GMX require a phone number?

In the realm of cryptocurrency trading and finance, user privacy and security are paramount. With that in mind, I'm curious about the onboarding process for platforms like GMX. Specifically, does GMX mandate the provision of a phone number during the registration or account setup process? Understanding the level of personal information required is crucial for users to gauge the platform's commitment to data protection and privacy standards. Additionally, it's essential to know if the absence of a phone number would hinder one's ability to fully utilize the services offered by GMX. Clarifying this aspect would assist potential users in making informed decisions about their choice of trading platform.
