Money is going digital,no doubt about that.The only question is when.Only the Fed knows...
money is already digital. nowadays we do everything with our smartphones. right now i just need my banking app in combination with the nfc chip in my smartphone to pay for things. that's all digital. i barely use physical money anymore since nearly all stores here have updated hardware that allows me to do contactless payments.
Yeah, and the day will come when we could buy any physical goods from any shop using bitcoins, and one day it will surely happen, at present the users of credit cards are more as compared to bitcoins, the reason is not many accepting bitcoins as a mode of payment, and once it is done, we will see many people using bitcoins for making payments.
