Whether or not you think climate change is an anthropological problem, the fact is there are climate agreements.
I see similarities between trying to control the world's temperature and attempts to regulate Bitcoin. To be clear, there are also essential differences: turning the world into a swimming pool is probably not a good idea, while regulating Bitcoin to death is probably a bad thing.
One of the similarities is that both limiting CO2 emissions and regulating Bitcoin aren't effective because there will always be nations laughing in the face of restrictions if that's profitable.
CO2 emissions are actually increasing despite billions of investments in renewable energy.

You could argue nations who cheat on agreements will be sanctioned, but they can just pull out of agreements with no repercussions.

What do you think, will Bitcoin be successfully regulated?
