Re: Pot meet kettle
You're right. I didn't make myself clear.
I found a nice example of what shall be done on the NY Times: http://www.nytimes.com/2012/04/11/opinion/ban-pure-speculators-of-oil-futures.html. Tricks similar to the ones described are used constantly to raise or lower euros against dollars against ... you name it.
Greece is on the verge of collapse - no matter what currency they use - but in fact they use euros, so why don't we bet against it.
Stronger regulation against betting money you don't have is a wise move anytime, and even today.
However, I am pretty certain that banks and traders will not accept stronger regulations, since, for better or for worse, they live and make profit this way.
Back to Microsoft.... They want to simplify their price catalogue using the same figures by stating that 100 USD = 100 EUROS. They're not alone in this.
