Until making a btc transaction becomes as fast and easy as swiping a debit/credit card at a point of sale, there is absolutely no motivation for customers to switch currencies. The infrastructure is already there; why reinvent the wheel? I agree btc is the more efficient choice, but unfortunately, it has a lot of usability issues to sort before it's ready for the prime time.
really right,standing in front of the merchant's local store about 15 minutes just only to wait the confirmation to be pop up is a really silly thing and people not going to do this unless there's zero confirmation features and we can make a transaction by scanning QRcode,it's different thing and it's fine
