We know Bitcoin is one of the powerful and top coin in marketplace.
But world wide all county are announced its illegal.
I personally think that bitcoin is very help us for paying any payment.
Its has many facility.
But our government are announced its illegal
Simply because Government has no control over it. People are freely using bitcoin and other digital currency without paying taxes in the government that's why they spread the news that bitcoin is illegal. But other countries already put a regulation on bitcoin.
