Few days ago a friend asked me this questions. But i cannot understanding that how to i give him answer. At last i said him that, bitcoin is an online currency. Only this currency used in online marketplaces. It is not possible to use it in offline marketplace like offline currency.
But what is your best answer of this question?
your answer is correct, because bitcoin is a digital currency that can be used when there is internet network, so if there is no internet network then bitcoin cannot be used ..
but despite bitcoin is online currency but you can use it offline. I mean like this many stores out there are receiving bitcoin as payment option and you can pay by bitcoin directly at the physical store. so you can not only shop on the internet using bitcoin but in offline or real world you can use bitcoin
