I think when people are talking about currency, inflation is referring to monetary inflation, not balloon inflation or price inflation. It’s the context that matters. 

“Monetary Inflation is an increase in the money supply which generally results in price inflation.  This acts as a “hidden tax” on the consumers in that country and is the primary cause of price inflation.”

Bitcoin fixes that. 

 Can you expand upon balloon and price inflation for me please? 

 Balloon inflation: Blowing up a balloon with air.

Price Inflation: When demand and supply change affecting upward revision in prices of goods or services. For example, supply of corn and wheat is curtailed due to bad weather causing their prices to rise.
