in my country is still controversial, the central bank in my country has banned bitcoin for financial transactions but still allow it for investment
I don't understand how it is possible for a government to allow it in investments but do not allow from financial transactions. This is ridiculous. In true sense governments can't control bitcoins and anyone can use it online. Many financial advisers who are against bitcoins are trying to declare it controversial on the basis of its uneven price which give sudden profit & loss to its holders.
