Bitcoin mining uses up all of the efficiency gains from energy saving over the past decade, and more. Bitcoin incentivizes carbon production by keeping electricity demand artificially high, even dedicating entire coal power plants to a single mining location. Therefore, cryptocurrency has already guaranteed we will never have time to advance on the Kardashev scale.
That's preposterous, Bitcoin incentivizes production of whatever energy is cheapest. That does not necessarily mean fossil fuels, though it is often that those are cheaper.
Hydro is a perfect example. A sizeable percentage of all Bitcoin mining is done with cheap hydro.
Bitcoin will do the same for nuclear, making it cheap and plentiful.
The components used for mining could have much better use cases and the raw material shortage does not make this easier.
I doubt that mining is the reason why countries/companies/people are pushing for that cheaper green energy.
Additionally, the cryptocurrency market right now is a mess, an online casino one might say, where only few can benefit.
And to push prices up, people are encouraging others to buy them, to push the prices up more and not because they believe in the future.
You people are advocating for shutting down one of the most important human advancements of all time – money that is directly linked to energy.
