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.
I think that true, paper money is essential for being a medium of payment in which it lessen the time consumes that transacting using bitcoin, I mean in small transaction it will be hassle if you have to scan their address for you to be paid vice versa . I think paper money will still be part of our daily lives since it contributes a lot in the society and also it is part of the identity of each country.
