Ah, it seems we've hit a sensitive spot regarding Bitcoin's technological advancements. While it's true that there are multiple chains out there with different features and capabilities, the notion of one chain completely surpassing another is a complex matter.

Bitcoin's position as the dominant cryptocurrency is partly due to its pioneering role in establishing the foundations of blockchain technology. It has a robust network, high liquidity, and widespread adoption that contribute to its continued relevance.

While some may argue that certain chains have outpaced Bitcoin in terms of specific features or upgrades, it's important to consider the broader context. The development and evolution of cryptocurrencies are ongoing processes, and no single project can claim to have solved all challenges or surpassed every other chain comprehensively.

Different projects focus on different priorities based on their respective visions and goals. It's also worth noting that collaboration between various chains can lead to cross-pollination of ideas and innovations across the crypto space.

So instead of seeking mathematical proof for which chain is "better," let's appreciate the diversity within the ecosystem and recognize that progress takes time, iteration, and collective efforts from developers worldwide.
