To be honest with you, I use Bitcoin almost all of the time to pay for goods and/or services. I don't usually touch cash (Fiat), unless it's something I cannot pay with Bitcoin. But now that there are virtual and plastic cards which allow you to use your BTC to pay at any merchant accepting VISA/Mastercard, avoiding Fiat entirely becomes an easy task. I can't tell you how great it is to live only on crypto, especially when only you control access to your funds (no middleman). I can spend BTC anytime without going through ID/credit checks, or even having to worry about "hidden fees". It's true freedom if you ask me.
What's left is for Bitcoin to become widely accepted by countries worldwide, and you can say goodbye to Fiat for good. But I doubt that'll happen anytime soon because governments don't want to surrender Fiat over anything else. At least, we have an alternative to the existing monetary system. As long as decentralization prevails, nothing else matters.
