Well, in this world where people actually care about the planet - you can't say this is any good...
https://edition.cnn.com/2019/06/14/tech/bitcoin-carbon-footprint-trnd/index.html Bitcoin is definitely spewing out WAY TOO much carbon dioxide and is going to kill us all. Can't fix it either because the entire notion of blockchain requires competitive mining. It is only going to get much worse as Bitcoin value increases. Total ruin.
I really think this is the death knell for Bitcoin.
Yes, Bitcoin's current energy consumption and expected future consumption figures are slightly higher. But there seems to be more ways to go around the world than unnecessary energy consumption. Carbon emissions have been increasing every year on earth. This carbon release was increasing before bitcoin was present. With Bitcoin, this figure continued to increase, of course.
Carbon emissions are increasing rapidly as countries prioritize their economic interests in industrial production. Moreover, although environmental pollution reports indicate certain countries, those countries do not make any regulations.
For Bitcoin and other crypto assets, a solution should be sought. But every individual, every company and every state in the world has to act jointly on carbon emissions and carbon footprints.
