Given past precedents, the USD should collapse in our lifetime (unless you are like 70 years old I guess) and we should see it within a decade or two.
The USD has already had a good long run and it's now on discount time. I don't believe the USD is any different from former attempts, it will not magically last another 100 years... it must burst and it will burst one way or another. It is then that the elites will have to decide if they want to enter another fiat clusterfuck or they want a neutral global asset class like BTC, and I believe BTC will be it, which will make BTC worth $1,000,000 each if you still want to value it in USD (due the debt default which is funnily enough around $21 trillion just like the total amount of 21 million BTC.
It's gonna stay marginal (at some level). At worst it could be used as virtual money for a video game (I don't remember the name: second life ?) At best it will remain a virtual currency used by geeks or by those looking to hide their funds (taxes evasion or other reasons) or on the darknet. that said, (besides that bitcoin needs to have a minimum value of $213,000 to hit to replace the US money supply)
Bitcoin is global. It could be worth $213,000 without necessarily replacing the US money supply, so no problem about that.
One of the best posts in this thread, would merit if I could. I fully agree that USD will not last much longer, so that begs the question which currency is going to take over? It's either going to be Yuan or Bitcoin. With all the investments and innovation plans China has from now till 2050 it's going to be a serious contender to the throne.
When we keep innovating, newer and better technologies emerge. AI, robots, IOT and much more are going to radically change the way we live right now. So imagine a super advanced future, I don't think we will still be using a FIAT currency as reserve currency. Perhaps USD will be replaced by the Yuan in the coming years and will eventually be replaced by Bitcoin.
