No, you are incorrect. The total supply of Bitcoin is known in advance, the fact that new coins are created until the total is reached does not make it inflationary at all. Inflation is the sustained increase in supply of a commodity or prices. Clearly there is not a sustained increase in the supply of Bitcoin over time because we know that firstly there is a fixed total supply and secondly the continuous supply decreases every 4 years or so. So calling Bitcoin inflationary at any point is an illogical argument.
