it will not far away that bitcoin will become legalize in many countries because bitcoin is famous with a very high speed and the rate of bitcoin is also increasing with quick speed and those people who are holding bitcoin and when the bitcoin become legalize in their country then they will get enough profit and they will then no need to convert to their country currency and use wherever they want.
Yes that is right. i think some countries have already accepted bitcoin as legal currency. japan is the best example with us. Still some other countries are also now planning to turn bitcoin as legal currency. I do not think that any country yet delar bitcoin as illegal, because not a sing country has yet officially banned bitcoin. i am sure that in future bitcoin will be consider as legal currency throughout the world. Not a single country will be there who wil will continue to bane bitcoin.
