Bitcoin maybe is the future of money because:
- it's inflation safe
- no corrupt bankers or politicians can manipulate it (easily)
- there are no men in the middle (edit: or only for a short time. Of course you should not save your bitcoins in a marketplace for a long time frame)
- it's cheap for all sorts of transactions
- it doesn't know borders (in democratic nations)
When the next bigger inflation of Euro or Dollar will arrive bitcoin exchange rate will skyrocket. Though that only means you should invest in it maybe it will also become money with exchange character in future.
