Bitcoin:
Spending is not easy(need some time)
Tracing not possible
Real money:
Spending is easy
Tracing possible
i think spending bitcoin for online transaction is much more easy because there is a lot of website are accepting bitcoin and its very good to buy something from anywhere and we can safe and secure our money in bitcoin because bitcoin is much more secure than bank.
I think what he meant about needing some "time" is the time in taking the transactions for it to confirm. Also if you think Bitcoin is better for online transactions think again as if you are not remembering credit cards and debit cards are the most widely use payment options around the web as they are the ones who provide fast and reliable transactions. Before you compare Bitcoin to Fiat you must have a solid claim as still the last time I look cash is king.
