The threat is in the form of increasing global warming which results in climate change. Generating Bitcoin requires a capable computer to solve complex mathematical puzzles and high electricity consumption. so that some countries prohibit mining for several other reasons such as in China and Iran some time ago. if so will bitacoin and others be able to run forever or is this just an excuse to change the green field to red..
It has been shown that Bitcoin mining uses like 0.x% of world's energy consumption and much of that is green energy.
We must ask ourselves - is the risk bigger with or without Bitcoin in our world?
- My opinion is that the problems Bitcoin solves are directly or indirectly much more impactful on the global warming. I agree that governments should incentivise and accelerate green energy utilization and off-setting carbon emissions, but that is no reason to "ban" or discredit Bitcoin just because securing the network requires energy. Almost everything today uses electricity and none bring the benefits of the Bitcoin network.
