Who are you blaming for being foolish? Practice more if you're inexperienced. Why didn't you dare to enter when it was at the bottom? Now you're chasing high prices at the peak and starting to complain. You should have entered at the bottom; aren't you regretting it now? Every time something goes wrong, you blame the domestic currency. Any currency that allows you to make money is a good currency; those that make you lose money are domestic currencies.
