Why is Polkadot worth more than Cardano?

Why is it that Polkadot commands a higher valuation than Cardano? Both projects are touted as innovative forces in the blockchain and cryptocurrency space, each with its own set of unique features and advantages. Polkadot, for instance, boasts its interoperability across multiple blockchains, providing scalability and security to a diverse network of chains. Its shared security model and user-oriented governance system further enhance its appeal. On the other hand, Cardano touts its robust security through rigorously tested protocols and scalability achieved through its Ouroboros consensus algorithm. Its Proof of Stake mechanism offers a more sustainable approach to consensus, appealing to those concerned with environmental impact. So, what gives Polkadot the edge in terms of valuation? Is it the breadth of its interoperability, the depth of its security model, or the efficiency of its governance system? Or is it perhaps a combination of these factors, along with market sentiment and investor perception? This is indeed a fascinating question that deserves further exploration.
