At some point in time I guess it will become either one thing or the other. It cannot stay both at the same time. Can it? Is it a healthy usage method to have it as both?
I think there are some place or country that has it already both.
They are using it for payment at the same time other people use it for investment .
There are already so many places that we could use our Bitcoin for payment method but the question here is are you willing to pay with your Bitcoin ?
Switzerland is the first country that comes into my mind, so possibly, it's doable.
Right now? I'm not willing to pay with my bitcoin, lol, the price is really going up, would rather hold it as a investment. But there are a lot of bitcoin supporters, no matter what the price, is using it as mode of payment though.
