I'm thinking since bitcoin is very used as a official currency on internet but still not used by many people since its popularity is still not that high.. What if on year 2026 is a the year where bitcoin is known by most people .. Do you think bitcoin will be used as a National currency on that year just like money that we used right now ??
personally i think that it will take more than 10 years to be national currency of any country, a people won't like bitcoin that fast, but lets say after 20 years, this can be possible

as each year more and more people show interest in bitcoins,so after 20 years probably everyone will know and will use bitcoins, so they will want to have bitcoin as currency
