Why will the dollar crash? What are the reasons for a total world re-alignment of currencies?

Over two years ago I heard that there would be, at some point, a total world realignment and revaluation of currencies and at the same time a crash of the federal reserve note compared to other currencies around the world.  Since then I have been watching many different factors that seem to fall into place to back that up, but have not been able to see the big picture as to what might really happen, or clear evidence that these revaluations and realignments are happening, that is until I ran across this article.

TF Metals Report has put together a serious accumulation of research and conclusions that fit with everything I have heard and seen to date that leads me to believe it is about to happen, and not only will precious metals go through the roof, but other paper currencies will go way up in relation to the US federal reserve note, to the point that it will become almost worthless.  You need to read this report and I would like to know if you agree with their conclusions and mine about what is coming and very soon.
