Thanks for your comment.
Concerning the dollar I think otherwise. As the USD is the most important reserve currency, most countries need to hold US treasuries to prove their solvency. China is not able to dump their holdings of US treasuries. If China would dump their holdings rapidly, this would trigger a collapse of the Yuan. The effect on the Yuan would be far bigger than on the USD.
Out of all fiat currencies I expect the USD to be the last to fall.

That is my opinion.. the FEDS are doing a great job at pushing the dollar down and soon people have started shifting base to hold precious metal or crypto.
