I think people find it more convenient to use fiat. That is what is stopping people from using Bitcoin. Why would I go to a store that accepts Bitcoin when I could simply go to a store that accepts normal currency.
It's convenient in a lot of cases but not all. Speed and cost are very important tactors taken in account when it comes down to financial transactions.
The bitcoin wallet should could use a revamp, followed by some a educational marketing campaign to create more awareness.
This could be the step needed for it to get more attention.
