If 1 BTC equals $1,000,000 then the worst problem will have been the collapse of the dollar...and probably the USA, which means the world would have gone to shit too.
For most people on the planet today, the world already is shit. If it's not to you, congratulations now check your privilege. For the billions of poor,
global capitalism is sucking the life from them.
Not so long ago the average person would believe that the loss the Divine Right of the King, and subsequent (ongoing) slow death of religion would be "the world going to shit". All the fruits of the age of reason would have been forsaken if the nobles and priests of the middle ages could have prevented the failure off Divine Right.
They could not prevent progress then, just as the banksters (our modern "nobles") can't stop bitcoin or the slow death of capitalism in our generation.
