If dollar crashes, no worries 
I think it would still be able to recover.
I think it would still be able to recover.
And until it does, what do you expect the world to do?
Do you expect the Sheikhs to accept dollars for their oil and wait for it to recover?
Do you think no other currency will be able to step up and take its place?
they will accept euro, in the maintime, or cny or the biggest fiat after dollars, it's not like there is only dollars out there
but it's better if fiat collapse because it was "sucked" into bitcoin, than in another way, so we have a real global currency to use
