Bitcoin was created to be a universal currency and lightning makes it possible to make completely P2P micro-transactions for a few pennies paid in fees.
Now let's assume for the sake of this poll that you could now spend your bitcoin that is under your control on your wallet, anywhere, by just tapping your bitcoin wallet (hardware or mobile) against an existing credit card machine and you are able to pay with bitcoin over lightning.
What I'm trying to understand and defend against a lot of the mass skeptics is this exact question - Would you use bitcoin as a currency if it was possible?
I believe, irrespective of the value, anybody that held bitcoin before 2017 would be in a place to spend it.
I rarely used my Bitcoin at all, in fact I am planning get more. Even if the price plunges it doesn't matter, I will still buy whenever I have the means. In terms of using it daily I don't agree with using it with just some coffee, It is the same as it was way back, the 10,000 BTC pizza, and maybe if someday it will be worth a fortunes millions or trillions then you would be probably the talk of the future people who spend their Bitcoin on a coffee. I would use my Bitcoin only if necessary like there's some grave illness that needs to be cured in the member of the family and there no more options to use.
