This is illegal in many countries. But many countries make it legal. They love Bitcoin. Their country started as a legal currency. So we think that soon Bitcoin is going to be introduced as the legal currency of other countries. Bitcoin has a bright future. It will not be destroyed.

For me government don't make bake bitcoin illegal worldwide because other part of the government is using it in their illegal work. Those that set it illegal are just scared that their wrong doings will be revealed once their people know about Bitcoin.

I feel that most of the nations around the globe don't see bitcoin as a risk, however rather they consider it to be something progressive. Time has demonstrated that and an ever increasing number of governments are starting to comprehend its esteem. They might at present want to control it however and force a couple of limitations all over. In the most dire outcome imaginable, in the event that they do for sure chose to boycott it, it would incite an immense negative reaction from the general population which would harm their notoriety and their opportunity to protect their administration which implies that this plausibility is exceedingly impossible.

Suppose that Bitcoin is legal all over the world and every trade is paid in Bitcoin, then there is a high likelihood that banks would be shut down. But it's the trouble of the banks to compete with Bitcoin, not of the governments, though the banks are important to the economy. It would seem quite an unsane competition if the governments ban Bitcoin to help the banks. In the supposed case, maybe the goverment would offer other kinds of aid.

Probably because there are only a few countries that have acknowledged or applied this bitcoin as a means of buying and selling in their country, so for now it is still not possible to apply it around the world

Government cannot control bitcoin because bitcoin doesn’t want to be controlled. It is the advantage of bitcoin that it cannot be controlled because of its anonimity and privacy. Also, if the government will control it, you have to pay taxes and transaction fees which can make transactions expensive. Bitcoin users love bitcoin because of its cheap and easy transactions. If you remove that, bitcoin will never be unique.

No government doesn't like money and the cryptocurrency industry is worth billions (or even trillions). I too personally doesn't see what are the advantage of making Bitcoin illegal worldwide but I do agree that regulations should be in place to a certain extend.

Bitcoin will be used throughout the world, whether it will be legal or not. And then who took it will be rewarded.

I agree with you.
The government will certainly not allow its citizens to use Bitcoin or Cryptocurrency because Bitcoin will threaten the existence of Bank Central.
If many people use Bitcoin then many people will not use Bank central services as their payment tool, they prefer Bitcoin.
Therefore the government does not allow the use of Bitcoin.
