Is there really a future for it? Where would btc be used instead of your traditional cashless money via debit/credit cards etc?
Debit/Credit money is not exactly cashless. It is based on the same framework as paper money is. It is the same system called FIAT money.
Bitcoin is something else, it is transparent and finite monetary system.
Of course it will be only more expensive over time - unlike every standard FIAT system - which will be worth less and less mainly because of two factors: quantitative easing and inflation.
