Why are some governments so keen to prove that bitcoin is dangerous. Recently, the Indian government sent notifications to the citizens that they should not invest in bitcoin.
probably because they cannot control it like a fiat money.(tax control, money flows, etc.) Btc made revolution during 2009 but nowadays there are more anonymous coins (like monero, verge). Banks state that it is dangerous to invest in crypto (maybe they are just concerned for their own future).

Banking sector is the real enemy of the market of the crypto currency because they have a clash of interest with them, now with no disrespect to the banking sectors from my side, the news which emerge from the banking side seems to be demoralizing and discouraging for the investors and the reason behind this is that they have already lost more than 600 billion dollars to crypto currency. My advice is better to stay calm and trust the bitcoin.
