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?
In the meantime that's not possible for now, we can only use bitcoin through internet or data connection then without it of course bitcoin will be useless at all. Meaning offline is not possible in any form of digital currency.
We will certainly need to have an internet connection no matter what happens in this world to regulate any of the crypto currency and to make any kind of transaction as well even in the future as well. There is no such possible way in fact using which you can use any of the crypto coin like the way you sue normal regular currencies in your daily life. Having an internet connection is a must condition that needs to be fulfilled.
