A global financial crisis (aka. initiation of ww3) means end of the life of many humans and animales. But climate catastrophe means end of all life on earth or at least all non extremophile organisms. Post appocalyptic paradise vs. mass extinction. Go for the death of most humans aka humanity. Fuck them. Lets be like the spartans, lets die for the higher layers of the system. Stop PoW-Bitcoin.
The bad thing: there is no second planet
the good think: there are tousands of possible ways to disintermediate the banksters without PoW.
