Real assets typically have a use value and an exchange value. Even if you can't sell such an asset (meaning it has no exchange value), you can still profit from it by using or consuming it (it does have use value). Fiat money, including crypto-currencies, are pretty special in this regard in that they only have exchange value, and no use value.
