Bitcoin is a decentralized transaction which means the system works without central authorities or a middle person. Government uses central banks to trace any currency movements, taxes and even illegal activities. Without being able to do so, government fears that illegal activities will easily get through and can’t be able to track them.

For Banks, the advantages of cryptocurrency are huge. First, the cryptocurrency allows people to trade directly with each other, just a small fee. When you transfer money through a bank, the service fee increases as the amount of the transaction grows, and when the amount of your transaction is large, you usually have a high fee. In addition, because of the mechanism of distributed bookkeeping, the cryptocurrency is not tampered with by anyone, and in the security guarantee, the encrypted currency will only be better than the bank.

As of bitcoin can not be controlled by any government because its more like independent, so i think government can not make sure whether bitcoin is safe for their citizents or not. Bitcoin built with high risk and high return so not any government can make sure that.

I don't think they fear bitcoin. They want to prevent their people of being scam and get involve into a high risk investment.

Simply because they don’t know anything about Blockchain, cryptocurrencies and ICOs. The issues of regulation and how to control its operation. There are other factors as well like how to impose taxes on it. Fear comes from lack of understanding and anything that looks odd and suspicious is forbidden to the government.

Bitcoin is a king of all Crypto currency, that is acceptable all over the world in a digital form, and highly demand in market exchange, that no have a central point of trace. With the government fear, has prove that bitcoin is real money

Well indeed government cannot control the bitcoin , and that's why i stay at bitcoin because it is decentralized , and one of the common reason why government fears bitcoin , they don't have the right amount of knowledge , they see bitcoin as a fraud a scam , a ponzi scheme , that's why they illegalize bitcoin.

Government  fears Bitcoin because Bitcoin cant controlled by third party,Bitcoin is an independent and based on blockchain technology which is more secure.Bitcoin made many millionaires and changed their lives.So government want to collect the revenue and tax.

yes it is true that many governments from some countries are banning and combating the use of bitcoin in the country but the possibility of the government there is still afraid of technological developments that increasingly sophisticated and possibly also the government under pressure by local banks because I think the most in disadvantage of this case is the bank because many local customers will be reluctant to save money in the bank again, they will prefer to keep it in bitcoin.
