i have same idea to make bitcoin offine (device have paper wallet which have 0.005$ bitcoin and user can pay using it ) but problem is bitcoin price changes fast which make this coin only waste of time
We all know this thing that bitcoin is a digital currency and we really need to have an internet connection for using it in our lives. There is no way that we can use bitcoin and that too as an offline currency. In fact, it is not only bitcoin when we cannot use as offline currency, but all the coins which are there in the world of crypto currencies do need an internet connection for their functioning.
