Wow that is very straight you talking here. What are the proofs for this to happen and is there anything that has happened in last ten years ? I think after ten years from now the bitcoin will stand the same it is today the only difference would be that it will be accepted by the government (may be). If that happens then it will only see one sure thing and thats its security of getting served as legal public tender. I think many other coins will become Hulk after the ten years so people may not be fond of bitcoin itself at that time. They will have lot of option to choose form and thus making it look like common currency of the era.
