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.
Thank you for your answer. But in order for btc to survive, or even thrive, wouldn't it have to be used a lot (at least much more than today)? And what is the probability of that?
I mean I have already bought small stuff with btc and it's neat because there are no fees etc for either side. But not many people have done it, I guess?
And why would it be only more expensive over time?
no not really. even if the level of usage stays the same in the future. bitcoin will "survive" even with the current price. because there is enough investors and also there is enough usefulness for it still.
but apart from all that, as it was also said before, bitcoin is still a new technology and as everything else it takes time to get adopted and grow to a level that price also rises with the mass adoption.
