I think legitimacy depends not only on technology. It also depends on the acceptance of the concept and how it helps people within the jurisdiction of the state law, they do not want bitcoin there because they know that bitcoin brings harm to their citizens as well as to the economy due to the fact that the bubble of things and volatility can occur in bitcoin but what I think now is that the state should be able to support by making the rules, because with the existing regulations Bitcoin market situation can be much more stable, indeed if applied it must be done by many countries because if only part of the country then I am not sure it can be smooth, therefore I really hope for all countries to know bitcoin even further.
