I think as much as bitcoin is a currency, it won't be as widely used as a fiat currency. Many people who use bitcoin also use it as an investment, and for that reason, they don't need to depend on it as a currency. I think there will be a lot of bitcoinatms available in the technologically strong areas, first world countries, etc., first. After some time, we might be able to see some ATMs popping up in other places, but I don't think the amount of BTCatms will be the same as fiat ones.
