How does synthetix make money?

Could you please elaborate on the mechanisms by which Synthetix generates revenue? I'm particularly interested in understanding how the platform profits from its operations and what are the key factors that contribute to its earning potential. Additionally, how does Synthetix's business model differ from other cryptocurrency projects, and what are the unique advantages it offers that enable it to generate income? Finally, how sustainable is this revenue stream, and what are the potential challenges Synthetix may face in maintaining its profitability?
