One big thing I can think of is that every time you use a credit/debit card, a transaction fee goes to a big bank/payment processor. With btc, it goes to a miner.
Other than that, how does it benefit you to use btc? I mean you need fiat to get btc, and then usually need to take fiat out. So where is the net benefit besides the fees being lost by the big banks/payment companies?
I don't want this is sound off-topic it is actually going straight to your topic. What I picture for the future is a world without paper and without a "wallet". This is getting there already with things like ApplePay and PayPal, but I think that BTC is more suited to the final stages. I picture leaving the house everyday with nothing more than my phone. It will have my ID in it and all my money. I think the way that BTC does this is better than PayPal or Google or whomever.
