I've learned something new today, it's my first time to read that word, "possibilism".
environmentally friendly.
If you will dig some of the old news, you'll see how many of those articles were tackling how mining is costly affecting the environment. They only look to that perspective but they never understand what they're saying about bitcoin/cryptocurrency mining.
In between the mining process was highly power consuming, but with continuous development the mining equipments with low power consumption and higher hash output have been developed. As in a quote compared to the environmental pollution from the mega industries what the banking and cryptocurrency network produce is very low. These days most of the mining farms were located on naturally cool regions to lower the power consumption and avoid separate power generation for the cooling purpose.
Maybe a survey or polling among the forum members helps in identifying how true is the possibilism theory associates with the cryptocurrencies.
