Inflation is the loss of purchasing power per unit, period. I know you are probably one of those "don't confuse me with the facts" people but 2 BTC bought a lot more two months ago, regardless of exchanging it for fiat. That is called inflation.
You can't measure inflation over a period as short as 2 months and with a single metric. What you experienced was volatility.
Inflation is a persistent and general rise in price of goods and services. You can not conclusively point to inflation for a change in exchange rate of BTC in a 2 month window. Compared to 12 months prior the purchasing power of BTC is much higher today. So are we experiencing deflation?
You have no idea what you are talking about.
Inflation
IS printing money. Printing money
IS inflation. If you don't print money, the average price of everything will not rise in the long term (because when money supply is fixed, and number of goods is increasing, light deflation is a natural thing) , unless there are some special circumstances.
This is why gold is ALWAYS rising in the long term - because the supply is rising very slowly, while number of goods which you can buy for it rises much faster (as we are producing more and more faster and faster).
