Yeah I course I would pay with BTC. BTC is not just for investment, it should be used for paying as well. after all it is a payment method. what is the use of Bitcoin if you can't use it. Hoping that we see more places using Bitcoin.
I am also looking forward with that scenario as well but it would be impossible if we don't take an action to mass promote the bitcoin to other people and teach them why do they need to adapt the crypto currencies and how do they adapt it as well. I think it would take a long time process of mass promotion but with a lot of effort we can achieve that goal as long as we are all working together and make progress.
