This is something like an interesting fact but nothing more.
It doesn't really matter what is the price of the national currenty. The most important thing is its stability. You can earn $100 per monts but you will be still more poor than the guy that earns billion of his cheap money.
From usability point of view BTC deflation is a bad thing.
I agree with the first statement. Comparing the value of currencies with each other without taking into perspective the economic fundamentals of each country, even something as simple as the CPI and the liquidity of these currencies is completely useless.
However, I don't agree with your statement about bitcoin's stability, and deflationary nature.
BTC will prove to be a better long term store of value than the majority of fiat currencies given the fact that it is unaffected by inflation, and currency debasement especially in countries where the banking system is not robust and the central bank uses their jurisdiction to finance governments. Furthermore, it is important to note that bitcoin is not deflationary - it is inflationary, just at a decreasing rate.
