I like paper money. I like to feel the buying power in my hands :p Bitcoin makes me feel like a robot. I am not saying paper money is better tho.
Paper money is one of the identity of every country. It has a physical form that can be used to purchase/buy some product that does not require bitcoin as payment. And every country will always keep and use it though bitcoin is popular nowadays and many are now engaged in it. Paper money is here to stay.
