People, please stop the fuddery. US$ is NOT going to collapse, not tomorrow, not the day after. Sure, CNY will most likely replace it. SOMEDAY. We will all be licking Chinaman's balls for money. But, it won't be for a while longer.
If US$ were to collapse, do you know the consequences? Bitcoin will be the least of your worries, then.
It will collapse, why else is the USA fighting for oil? Oil and military are the only two things that are backing the value of the US dollar. The USA is losing their military supremacy and their 'monopoly' on oil.
The question is not if fiat will collapse, the question is when.
And what exactly is supporting the Euro? A bunch of countries that can't come to an agreement on most monetary policies and several countries that have a HISTORY of defaulting (the US has never defaulted). What exactly is supporting the yen? An aging demographic and over a decade of stagnation? I could go through the whole list of fiat and countries and poke holes in what is "supporting" them. If you honestly think the USD will be the first to collapse, you need a few more economic classes. If you honestly think ALL fiat will collapse and the world goes on like normal, you need your head checked.
All fiat money will eventually collapse. And to say the USA never defaulted is not entirely accurate.
First, we had the gold standard, were gold served as international currency and every currency was backed by gold.
Then the USA invented the scam known as the bretton woods system, on which the USA defaulted.
Now we have the petrodollar scheme, an even bigger scam, and the USA is close to defaulting on that.
It's not a race between which country had the best fiat though, because all fiat money is a scam and they are all doomed to fail. Put your trust in bitcoin, gold and silver, not in wordless paper.
It's quite sad really that you know fiat is backed by nothing at all, but you still believe in it, to the point where you even call me an idiot for thinking outside the box. Goes to show the power of indoctrination.
It's alright buddy, keep watching mind numbing TV series and keep voting on presidents, they only want the best for you. They will totally not take your rights away with lame excuses like counterterrorism and financial problems. Ah great America how glorious are you, you're the first and last empire that will last forever, and the first one to conquer the galaxy to spread it's glorious peace and democracy.
