Transaction fees are a real issue with Bitcoin.

Most of the time, they are suitable for standard payment amounts, but they can spike to quite high levels that make only large amounts worth transacting. This is due to network capacity limitations.

Furthermore, anyone that does not wish to hold BTC - understandable due to its significant volatility - must convert it again into the preferred currency.

Fees = friction, and there's enough friction now that people will only use it when it provides some significant utility.
