Yawn - if the dollar crashes bitcoin is not going to save you. That is the only fact here.
P.s. The dollar is not going to crash any time soon.....
I think we can agree to disagree about the dollar collapsing, it's almost a mainstream idea these days.
But let's imagine the dollar started to collapse, it won't be over weeks it will be sudden and violent. What would you do and what would you advise your froends and family to do? if a bank run happens it will be an online bank run, no queues outside banks. In 24hrs most people would have time to move their money to some kind fo online Gold account which usually takes time to process or people will scramble to Bitcoin. I'm not saying everyone will, but enough to send the price way higher than people imagine.
