What makes AVAX valuable?

Could you please elaborate on what factors contribute to the value of AVAX? I'm particularly interested in understanding its unique features and how they translate into economic value. Is it the scalability of its blockchain? The robustness of its smart contract functionality? Or perhaps the strong community support it enjoys? I'm also curious about its potential for future growth and adoption. Could you share your insights on these points, and perhaps also discuss any challenges it might face in the cryptocurrency market?
