There are many differences of bitcoin and real money.. bitcoin you can use it online as alternative real money you can buy anytime there.. in bitcoins you should have too because many other will exchange it fast and instanly in our place.
Yes indeed. In my opinion and addition for all you've just stated is that real money can be used anywhere you buy but Bitcoin there's just selected stores that accept Bitcoin because the value is just so high. If you save money your money will just grow whenever you put something in your savings. In Bitcoin you will have both savings and investment in this case you will have profit in Bitcoin while saving it at the same time.
