Money can be used anywhere in the world without the Internet, and bitcoin only in the presence of the Internet and then not all countries accept payment using bitcoin.
But bitcoin is also money. If you dont accept it as money then you are making mistake. There are several forms of many and the Bitcoin is one of them known as the digital currency. Adding to this, by definition it can be said that the bitcoin is money but we have governments who manipulate the words and making the confusions for the people whether to call it money or not.
