The way I see it world government's will not allow uncontrollable currencies to thrive in the world market. Current fiat currency is how they have controlled the world for ages and they are not going to just give up that control. They way they maintain the control is through taxes, and exchange. As long as they have the ability to ban the exchange of 3rd party currency from current primary they can kill what ever currency comes their way.

That's how they kill bitcoin, by taking away the ability to exchange it with primary government currency. They can keep any business from accepting it by 1 making it impossible to exchange for government currency what ever that may be.
2. Making it impossible for the business to pay taxes with it. If they can't pay taxes with it, and they can't exchange it into something that you can pay taxes with. Then its worthless for them. Intern its worthless for us. It will only ever bee a p2p currency.

Bitcoin and all associated, blockchain crypto  currency is never going to be allowed to thrive unless world governments can control it. As of right now they can't and so you will start seeing exchanges being killed one by one.   

That's my opinion. Do I own bitcoin yeah... lol I hope it works I really do. I just doubt it.

What is the point of making the bitcoin illegal throughout the world? Why want to bring the bitcoin closer to the authorities and the state? It is precisely its interest, make it available to all and avoid any intervention of the state in ... Countries should have no rights on it and therefore should not judge whether or not they find it legal ... there are really people who have a hard time understanding the principle ...

Yes, just simple what I think government has also have an interest in bitcoin that other countries bitcoin has been legalized already. As we all now bitcoin has become the mainstream that caught the attention by many. On how it can help the economy if it will be legalized.

Governments can't really control Bitcoin, so they can't surely illegalizing it, because it is decentralized. They can't stop their people from dealing with bitcoin or trading it, simply because it don't need identification, and everyone with Internet connection can use it without any issue.
Also i don't see why governments have to ban Bitcoin, its helping so many poor and unemployed people around the world.

after all every government and state has different rules and views dude. just because one country prohibits the use of bitcoin does not mean the whole country should also follow to ban bitcoin right? every country will have a discussion first and very likely will have differences of opinion and policies

Government knows the importance of bitcoin and its trading there is no reason to mark it illegal only on asking of some people who don’t know about it. No state will like to avoid or miss an opportunity for earning decent profits just by working with bitcoins. Bitcoins have massive support so no one is going to declare them illegal.

On what legal grounds?

Maybe in a totalitarian communist regime bitcoin can be made illegal, but in the free world a legal case would need to be made. I have never heard one, have you?

First of all, this world has not only one government so bitcoins can be illegalized by some governments but they can't push remaining world to follow their orders. Secondly, bitcoins has improved the economy in a dramatic way which is good for one's own country. Third, bitcoins come under no one's control.

It is right that some governments don’t consider the matter so serious but no doubt that the interest of the people is growing very fast and the day will come close soon when every government will worry about bitcoin popularity.

I think currency less people as compare to world population are known to bitcoin that’s why governments are silent now.

One thing is also here, if governments want to declare bitcoin illegal worldwide, but they can’t take any action against bitcoin nor control bitcoin because bitcoin is decentralized safe currency.

You don't need to live in a totalitarian and communist regime to experience banning of something. In EU for example, laws have been voted to ban glyphosate (Monsanto Roundup) use for example. In some countries of the free world some gov's plan to make the use of a bicycle with helmet illegal so why not BTC ? If a government judges it as a tool for money laundering they can decide to vote a law to make its use illegal.
