I think this fact will happen in this year. After Trump 's inauguration , Bitcoin price is rising up higher and it's quite closer to 1,000$ price. it seems the world economy is ready for new crisis when USD is down badly with Trump's decision and it has effected to bitcoin price immediately.
what you are saying is highly speculative. and i have been hearing it for many years about USD value dropping and failing economy of US, and i am not saying it is never going to happen but i have never seen any valid argument and it has not yet happened
In fact, you just haven't been watching closely enough
Most likely, you refer to the ultimate dollar collapse which is a speculation bordering on wishful thinking or outright bullshit, but if we refrain from sweeping assertions and start talking about the dollar value behavior, this is exactly what happened during all 2000s. You can see that yourself at the historical USDX value chart below which shows the value of the US dollar against major currencies over time
As you can see, the dollar still has a lot of room to go down
