I'm wondering this because is such a real threat to bank system and we all know how banks and governments are tightly linked !
BTC could make people more autonomous, self-resilient, being their own bank. You can use it like cash, making your transaction almost untraceable (or untraceable using e.g. monero or dash or laundry systems) : this is governments worst nightmare, isn't it ?
Mostly the real reason why should the government,can't declare bitcoins illegaly to operate worldwide,because they know the main purpose of cryptocurrency then why should its been created is to cultivate economic growth and promote social responsibility globally and not to create havoc or some illegal activities in the worldwide market,as just what like other thinking of cryptocurrency investment.while in other hands crypto is not a threat to the banks,instead its will help collaborate in banks to promote the world currency monetary fund.
