bitcoin can be used like paper money so I don't that there is any difference between bitcoin and real money as you can use it for online
Personally, I love the opportunities that bitcoin has given to every single person: you can just pay your friend through the web without any problem at all. I have had such a situation, where my friend from abroad have made me some kind of a graphics. Using bank transfer system would be annoying, and I have payed him almost instantly with bitcoin!
