Hi there, I appreciate your thoughtful response and I can understand your concerns about the resilience and fragility of blockchain, especially in the context of your country's electricity issues. You raise valid points about the dependence of blockchain and cryptocurrencies on electricity and internet access, which could potentially limit their effectiveness in certain situations or locations.

However, it's important to note that while blockchain and cryptocurrencies do have their limitations, they still hold the potential for significant positive impact in many areas. In fact, blockchain technology has already demonstrated its utility beyond just cryptocurrencies, such as in supply chain management, digital identity verification, and secure data storage.

Moreover, as technology continues to advance, solutions are being developed to address the challenges you've mentioned. For instance, there are efforts to create decentralized internet and energy networks, which could make blockchain technology more resilient and less dependent on centralized infrastructures. Additionally, innovations like mesh networks and satellite-based internet are being explored as ways to provide more reliable connectivity in areas with limited infrastructure.

As for the concern that those in power may try to shut down blockchain-based systems, this is indeed a risk. However, the decentralized nature of blockchain makes it difficult for any single entity to control or shut down the entire network. The more distributed and diverse the network becomes, the harder it is for anyone to manipulate or tamper with it.

In conclusion, while blockchain and cryptocurrencies may not be a perfect solution to all the problems they aim to address today, they still have the potential to bring about significant change in various aspects of our lives. It's essential to acknowledge their limitations while also exploring ways to overcome these challenges and maximize the positive impact of this technology.
