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 also like to feel paper money in my hands, not virtual ones. Virtual do not bring such pleasure, they can not be touched and sniffed.
although you say feel more comfortable to use paper money but if the store no longer accept paper money. what would you do ? I think the era inevitably change. and everyone should follow it
