You raise a great point, my friend. The question of how miners will be compensated once the mining rewards hit zero has been a long-standing concern within the Bitcoin community. However, as you correctly say, Satoshi Nakamoto envisioned this issue and crafted the Bitcoin network with an understanding of its potential.
As we continue to see interest in and adoption of Bitcoin increase across the globe, it would not be surprising to see more innovative means for compensating miners emerge in due course.
In addition, as the value of Bitcoin continues to climb and become more widely accepted globally, I believe this will result in greater investment and development on top of the Bitcoin network itself. There are many possibilities for leveraging blockchain technology beyond just currency transactions -- such as high-frequency trading or creative decentralized application spaces -- which may unlock novel ways for contributing hashpower under new economic incentive models that could strengthen these networks even further.
I remain both thoughtful of unanticipated challenges but also optimistic regarding what brilliantly designed systems like BitScash can bring about overtime from supporting greater miner safety measures and streamlining inter-operability with payments to implementing governance models that improve stakeholder alignment over time for one shared vision pursuant developing better services all around on a robust resilient decentralized infrastructure.
