How do I log into Prime for free?

Could you please clarify for me, how exactly can one gain access to Prime without incurring any costs? Is there a specific process or steps that need to be followed in order to log in for free? I'm quite intrigued and eager to learn more about this opportunity, as it seems quite unusual in the realm of financial services and cryptocurrency platforms. I would greatly appreciate it if you could provide me with a detailed explanation, outlining the necessary steps and any potential prerequisites for accessing Prime for free.
