If that would have been easy then it could have been already being followed everywhere. But its not! Merchants fear because they have to track the sales, earnings, pay taxes and much more. There is no provision for this purpose yet and thats why they might not just accept it so easily. For customers it gets difficult to wait in the coffee shop until they get sufficient confirmation of the bitcoin process. So there are not single but many problems in using this currency. Until the time we dont see huge set up for this then we cant see any progress as whole really.
You are absolutely correct! It is hassle free if we just need our cellphone, the internet connection but as to the proces it might take time. There are just things in this world that crypto currency will not make it easier, just like what you said, purchasing a coffee, or anything that can be quickly done with our fiat money. Most especially when there is a problem with the internet connection.
Well, the best important thing to make it be possible to happen is the use and presence of the internet connections. No doubt, this will be a chance to happen but maybe it takes much more time because like what some other's said it is not an easy things and there's a lot of things that we needed to consider first. But if it will be happen, I believe that it makes benefits to us most specially in doing transactions.
