Ok, I read all the thread and although I didnt understand everything I read, what is wrong with this possiblity?
If/When Greece defaults on their debt, the worlds banking will all take a hit, because they are so inter-twinded, dependent on each other, etc. because of international banking.
This will put a hurt on the banking sector, their stock will decline, thus people will be looking for an outlet that is safe and the price of gold will increase rather quickly.
