We are entering in the new type of economy where price predictions are not possible any more because productivity and prosperity of humanity will rise to the new golden age level. Bitcoin will go to 1 million dollars in 2018 and is being used by central banks as a global stardard ledger - dollar will fade slowly those who buy now will become the new wealthy elite.
It is possible in the future when internet will be available for all people in all walks of life. When that happens the new generation will be cashless. I think there will be easier and faster money transactions.
