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.
In my own opinion, the reason we are using paper as a money because it represent as an object and it is more comfortable and easy to bring and put it inside your pocket or wallet, instead using precious rocks and metals as an currency. Today, a lot of people are now using virtual money to use as an payment transaction instead bringing your wallet, you only need to bring is your phone.
