Just want to share the details about the people who ever thinks that why we need to use just paper as currency and we all are working hard to get those paper.People claiming that bitcoin is not virtual so it cannot be considered as money or they call it as scam or ponzi but they are using just papers for centuries and those paper currency were made out of thin air.
I also thought like that, but whatever the reason, money is only a tool used to make it easier for everyone to make buying and selling transactions, using paper to be an exchange is a good thing because paper is not heavy and can be carried anywhere.
