The bit about the dollar taking a beating in the markets over the last week is largely true, but I think that the transition sentence "The speculation on the future of a new North American currency came amid a major U.S. dollar sell-off worldwide that began last week." is an incoherent connector between the fact about the dollar's slip and the dubious idea of a displacement of the dollar for the "amero".
Whoever thought,'In God We Trust' would be written so small on our new one dollar coin, you have to use a magnifying glass to even see it. Beginning of the end for that phrase? The first step in removing God from our money?
"I don't think that this is a credible article about the "amero". There's just nothing to this weird idea."
Yes, there is something to it, and it isn't just an 'idea'...
