likely due to the sudden recent uptrend in interest in bitcoin. that confidence in bitcoin is rising, it would be foolish for the government to stand idly and watch the dollar devalue against the bitcoin.
That is true if we need that bitcoin should grow in future then we desperately need the support from government and society to accept is as a currency for the mode of payment.
It is the fact that people trust fiat more over the bitcoin as they are used to it and credit cards are so much in demand nowadays that people don't want to get into bitcoins as they are not aware and that is the reason they don't trust bitcoin as a currency.
