as we know, many governments in the world are banning bitcoins and here I have my own why the government want to kill Bitcoin, because I think Bitcoin can be used for terrorist financing, money laundering, illegal weapons purchases, crime and tax evasion. therefore the government forbids Bitcoin, because Bitcoin transactions are difficult to trace so it is only natural for me if the government is very worried about Bitcoin and many country banning (block) Bitcoin.
but this is just my opinion, so if I am wrong I apologize.
Thank You.
Government ban bitcoin because as you said many people take it advantage to use it to make a fraud to other and also they want to control it that's why country ban the bitcoin because they can't control it.
