The circumstances and timing (it's been a while) suggest we are probably closer to a crash happening.
From a loan/interest point of view, the dollar de-valuating a bit is actually not a bad thing for the US. It stimulates exports and inflation. And at the same time that reduces the value of the debt (and that is paid in dollars). The downside is that inflation going up usually also means interest going up. And Trump resisting that because he wants to accelerate the economy might not be a good thing.
The big picture here is oil. The world is slowly moving away from oil as the key driver for economies and paying for it in dollars. China is well on its way electrifying large parts of its economy. To the point where it is starting to import less diesel. And they border on Russia with whom they trade in Yen, not dollars. A world that is going to trade less and less oil is going to be less dependent on dollars.
I'm not an economist though. But planning for some kind of crash/correction seems prudent.
