My opinion about the growing Russian Domination in Bitcoin mining has potential geopolitical implications. As Bitcoin continues to gain acceptance and adoption, countries with significant mining power may have more influence in shaping the future of the cryptocurrency. This has the potential to give Russia more leverage in global discussions and negotiations involving Bitcoin.
That's not how decentralized networks function, most of the mining hashrate coming from a particular country does not mean that country has any influence on BTC, it is either the country accepts or ban mining, that's the limit to their power or say in it, if they accept mining, and they have cheap energy, many miners would mine there and more would migrate to the country, but if they ban mining, miners would move out, some will shut down and others will mine secretly.
What kind of global discussions or negotiations regarding BTC are you talking about, do you mean summits or meetings where world leaders decide on regulatory framework for BTC? You think Russia would be in support of BTC in summits like this. Centralized governments only support what they can benefit from, and BTC is decentralized and can't offer anything to them, so they rather be neutral or be against it.
