كيف الكميات كسب المال؟

Could you please elaborate on the methods employed by quants to generate profits? I'm particularly interested in understanding how they apply their quantitative skills and expertise in the realm of finance and cryptocurrency. Are there specific strategies or models they typically rely on? How do they identify and capitalize on market inefficiencies? Additionally, could you discuss the risks involved in this process and how quants manage them effectively? Thank you for your insights.
