This is the problem with bitcoin at the moment and all other emerging cryptocurrencies.
Consumers are not going to take an extra step to buy Bitcoin, so they can then go out and buy something that they could have already bought with the debit card in their pocket. This is not going to ever happen. It would be like asking someone to go to the store and buy a can or petrol for their lawn mower, when they already had a can of petrol in their garage.
That's why currently, people are interested in Bitcoin for three primary reasons: speculation, novelty, and making darknet purchases (places debit cards don't work). In my view, the way to change this is for the community to embrace and promote services/methods that allow consumers to receive their wages in Bitcoin.
i sure don't do that. i own bitcoin because i believe that "trusting in god" for the federal reserve to print and control money is a failed experiment.
