Re: Do you think that Bitcoin could become a popular payment method?
no it is nothing like gold. because you can never use gold dust to buy something even if it is valuable since the other party can not easily verify the authenticity of the gold dust. it may be rust for all he knows. but with bitcoin he can easily verify it and never get scammed and you can use a small amount of bitcoin 
I was referring to its value. Of course Bitcoin is better than gold thanks to blockchain technology.
I can see that you like giving answers looking for irrelevant details... What do you think about my question?
if it is irrelevant why did you say it
and i already voted, i forgot to also mention it in my comment. .... i think it will be a popular payment method in a couple of years. specially with Lightning Network active and possibility of fast and cheap micro payments. and as bitcoin grows more, its price becomes more stable and that helps with the first part of my last comment, it removes part of the greed so people are more willing to spend it.
