Government see bitcoin as a threat specially to its income tax return plus being decentralized and uncontrolled by them is enough reason for them to stop it. The government wants to control everything within their grasps plus they just always fear the unknown, we all know hear that the danger does not come from bitcoin but from other people who choses to scam which they always do not just in cryptocurrencies but to every thing they can exploit too.

I think Since Bitcoin is a decentralized virtual currency so that it can't be controlled by any authority or government, another thing is, Bitcoin is becoming more popular than conventional banking system or capital market, that's why people are getting engaged in this platform day by day.

Naturally, every government wants to suggest people using a centralized currency that would be regulated, in this way, some countries government doesn't support Bitcoin platform for their population. On the other hand, Bitcoin doesn't require any income tax or fee so that government is becoming deprived of gaining tax. one thing we can consider for a reason that Bitcoin is being replaced by the traditional banking system. so that it's becoming popular more and more. that's why they are afraid of Bitcoin revolution.

For me in bitcoin i dont have any fear its because bitcoin last until now since then.So why should i feel fear? Based on my experience also in bitcoin it is good and i cannot feel any fear because of the good experience that i have.

the fear of bitcoin is when bitcoin values go down and make worries moreover if bitcoin decreases drastically it's very worrying

we do not have to worry about india, because even without india bitcoin will still exist 
and every country has its own rules, lucky my country receives bitcoin well
there is no ban on investment in my country, the government only appealed, if bitcoin is a high risk investment
that is it

The government does not benefit from bitcoin, since it cannot be controlled ...

There are some positives and negatives about bitcoin but it depends in the perspective of the country but i think in the case of india they saw the bitcoin as a threat to their economy and it may affect the growth of their economy. So here are my ideas why a certain country ban bitcoin or won't let the bitcoin goes to their country.

1. It can be used to illegal works such as to hire, buy illegal drugs or guns, etc.
2. It can be used to money laundering.
3. The local banks will end in bankruptcy (since lot of user will going to use bitcoin)
4. The government can't put taxes to the workers of the cryptocurrency industry.
5. The deepweb or blackmarket may become powerful.

We can't blame the government because of it, it may really affect the economy and it's better to resolve it early before the government can't control it right?

I have the same opinion with you. The governments banned bitcoins because they wanted their country to be developed and peaceful. They do not want any wrongdoing in their country.
Although developed countries block the bitcoin and affect our economy, it is justified. I fear that in the future there will be more countries banned bitcoin and the crypto market will be devastated.

why not invest in bitcoin ? bitcoin has low supply,
it will increase as the time passed by with the demands.
their logic is wrong.
