Many countries do not recognize the currency attributes of BTC because they are afraid of the impact of BTC on the financial market!
Bitcoin is the currency that is earned through labor time!
If everyone agrees with Bitcoin's effectiveness like gold, then the world will produce a fairer financial order!
To me i think that it will take some more time, when bitcoin will become a legal currency there, Bitcoin is the new emerging currency and in future it is expected that bitcoin will be use as a universal currency, but still and therefore even those countries who do not yet turn bitcoin a legal currency very soon they are going to make bitcoin a legal currency in their country.
