From what I understood in the article of the link you attached, I'll say this is more of a partnership move from the government than outright taxation.
The Kazakhstani government simply want to align incentives instead of increasing what the miners in the country are currently paying for electricity.
I think it'll be beneficial to both the government and the miners if miners will get predictable electricity costs while the government gradually builds a Bitcoin reserve.
That said, I'm a bit sceptical that the agreement when reached will remain attractive between both parties in the whole 10 years since we all know that energy costs and Bitcoin price can significantly change within that period.
That is very true. With that being said , I would say they can always update their terms of agreement accordingly. As prices change as well as the value of the money, both parties should come up with fair terms in which both camps will benefit. They should have the win-win situation here, otherwise, their partnership won't last as the other party might give up if they are not getting the right income for themselves.
Can you give an example besides this, because China used to keep the dollar in reserve earlier and later it sold all the reserves and bought gold. Just so that it would not fall under the pressure of America and that's why it has now stopped recognizing Bitcoin so that no country can impose its rule on it.
Sure, I'll give you another example. Prior to 2022, Kosovo was a country whose policies and regulations allowed and encouraged crypto related activities and mining. Because of the low cost of electricity then, it became a lucrative location for miners, however, everything changed it 2022 due to the high rise of energy price after domestic coal-fired plants suffered outages, to manage the situation, the government authorities had to put a complete ban on crypto mining
https://www.bbc.com/news/world-europe-59879760These are the kind of unforseen circumstances I am referring to, so you can see its too early to celebrate. Today mining it Kosovo is completely illegal.
This is a very good example that circumstances will really change the scenario as they need to adopt the current happenings in their country. We can't really say that the regulations will always stay that way because unforeseen scenarios will forced them to implement a radical change to compensate for the current situation.
