The pic was the ten year chart of USD to PHP which shows a trend of dropping from 55 to 39. I did not notice the currency war thread. I probably need to post it there. What I am seeing is that large countries with sovereign currencies tend to float and deflate, while larger countries tend to peg to USD and inflate. I just think the smaller countries would benefit from Bitcoin to attract commerce since their exchange rates are undesireable.
I dont think that this conclusion can be drawn. The value of a unit of a currency long term is mainly the supply: the number of money units issued, combined with the fractional reserve bank money extension, and the demand: the number of people using the currency and their money holding preferences.
