I'm exploring the topic of global hash rate distribution in Bitcoin mining and am looking for resources or insights from those knowledgeable in this area. Specifically, I'm interested in:

Current Global Hash Rate Distribution:
 * Is there a resource or study that shows how the Bitcoin network's hash rate is distributed globally?
 * What are the current trends or notable changes in this distribution?
Dominance of Certain Countries or Regions:
* Are there any reports or data sources that detail which countries or regions currently have the highest hash rate contribution?
* What factors (like energy costs, regulations, technology) are influencing this?

Any actual links, studies, articles, or personal insights on these points would be greatly appreciated. I'm looking to gain a comprehensive understanding of the current state of hash rate distribution across the globe and its influencing factors.

Thank you all in advance for your help and contributions!

Best,
