The problem with fiat from most countries is that it loses value over time because of inflation. Bitcoin should gain value over time.
Yes, that is one reason because many persons are using bitcoin. At this moment they are using bitcoin as investment, not as a daily currency. Fiat loses price, but it's necessary if you want to live in society.
For now bitcoin will continue being a investors currency, and only who wants to invest will use it, as there aren't many stores and sites accepting it as payment form. Because of it many persons compare bitcoin to gold too.
