No bitcoin will not be used by everyone ever. It can reach a high percentage of people if it continues to grow but it can very easily fail aswell depending on future events.
For now it would be great if a little bit more people would use it so we could get more shops supporting it.
that is just bullshit mate, in my opinion it is really going to be possible in a few years if the adoption gets even faster than it is right now, and if it is not going to happen in a few years then i think that in a decade it is going to surely happen, that would be great for me
i think mass adoption is the best for all the holders who are planning to make some good money out of bitcoins with their investment because if the mass adoption would happen like that they would surely make a lot of money
i believe that in 6 years it is definitely possible that bitcoins will become really mainstream and it might even replace some of the currencies, that would be really great because the price of bitcoins would be really high then, i cant wait for this
