If the support breaks, I would stick with USD:
I was looking at that chart as well and saw the actual price near support level.
I live in Greece and there is a lot of talk about Greece, that it will finally exit the Euro Zone (some say it might even happen as early as next month). My concern is that the Euro might crash in case of a 'Grexit' which would make it break the support level and plunge quite low.
I also know about the economic situation in the US and would rather not have USD as my account currency.
The question actually is, IF the Euro crashes, which other currency or currencies are more stable and would be less negatively affected by such a crash.
