Everyone would like the bitcoin is accepted in all online and real stores and, as as mentioned in the title, what would happen if Bitcoin became a legal currency?
Yes it's true everyone who are using bitcoin would like bitcoin to be accepted by the government so we can use bitcoin to buy in online stores and real stores. If bitcoin became a legal currency we don't need to convert bitcoin as a real money and we can now store it or put it in the banks.
You can trade now with bitcoin. You have no limits to it. But never bitcoin will not be recognized as an official currency. The only way is to buy an uninhabited island and establish there a state official currencies to bitcoin.
