I agree with your strategy.
One thing I read recently here on Steem is that the dollar has a lot of life left in it.
As more and more currencies begin failing, people will shift their funds to the dollar.
Essentially ... the ships are sinking. As the weakest ones go, their value will shift to the strongest ... the dollar. This will prop the dollar up for an extended period of time ... and maybe even give it an upward price pressure (literally or relatively) ...
Additionally... I don't know how much longer Bitcoin can be held under water until more and miners are forced out of business.
We will see.
