It's still only 1 government. This is certainly not the worst that can happen as governments never work together for a common cause, unless it's like a nazi invasion
The worst thing that can happen is if the security gets defeated, someone finds a way to infect the blockchain with a virus or breaks the encryption. Remember that external bans mean nothing as long as the fundamentals are in place. If your country bans it you aren't left with nothing. You can always go to another country and trade it there.

That is nothing, governments are going to do that at some point but when they do that it is likely the economy of the world will be crumbling and their power with it, besides while many people obey the law and would like to do so, if the choices are to eat or to follow the law 100% of the persons will choose the option that allows them to eat and be healthy and live for another day than the option that only looks for the self interests of the governments of the world.

Well it does not really the only worst case and best case scenario. But as you have stated, when in terms of government control, they can not do it, but it may have a conspiracy in group of rich people. Capitalist are always doing what they can do in order for them to stay on top and that is the problem of today. On the other side, bitcoin will be more great than the current currency of today and that will be a very good thing. As of today the thing that will happen is the rise in the market of bitcoin.

Best case scenario for Bitcoin is the price go to moon like $500k and the people would kill themselfs WHO has no bitcoin, and the worst case scenario for Bitcoin is the bubble and explose.. Anything can be happen in this World right now so i won't be suprise in any case but i wish to rising because i am bitcoin holder

The government might be able to continue to let cryptocurrency remain, and not accept the virtual currency as a payment instrument, and that is a situation that I think must be done. But I suspect that sooner or later, the government will try to disappear from its existence.

The potential for government regulations about Bitcoin is most likely to exist, when many countries have limited access to or exchange of other Bitcoin and cryptocurrency. China has been known for banning ICO (Initial Coin Offering) and limiting access to Bitcoin exchanges.

Keep in mind that Bitcoin is not anonymous at all. Users routinely make mistakes that weaken or eliminate anonymity from Bitcoin. As previously reported, the IRS has run services from the Blockchain analytics company Chainalysis to help find potential tax fraud for those who do not report their Bitcoin profits.

India has become the umpteenth time to try to get rid of Bitcoin by filing lawsuits because of its anonymity. Advocate Bivas Chatterjee asked the court in India to immediately regulate the outflow of Bitcoin in India. It believes that Bitcoin is difficult to track and is the vehicle of choice for illegal financial transactions and other criminal acts.

However, countries with large economies such as Japan have considered that Bitcoin itself is a method of payment in the future.

Well theres only movements here in crypto world, the worst case is when it falls down deeply and the best case when its rising up and surpass the current price, but there is no worst case if you know how to handle coins, if it falls down just hodl it and wait, be patient, make sure to sell it if you can surely earn profit.

1. Best case scenario: by 2020 we are back in bull market; people gain confidence, no such thing as one big wallet controlled by one person or unknown company, but a big, important entity and conglomerate of trusted companies, making this known as digital gold, offering the fundamentals and support for the market.
2. Worst case scenario: Bitcoin fud increases, we get back to 2014 where soldiers witness stuff that no child should know, doom levels get down beyond hell and chills, in drops that just makes the hell implode. In other words, what we see now is a stubborn bitcoin and altcoins turning ghosts of the past.

  To my view I think the worst case scenario for Bitcoin may be this year that is 2018 we have  seen signs of risk taking in the market .We have also seen Bitcoin recovering rapidly and it also shows an upward trend . Hackers can wreak havoc on the Bitcoin market a failure,theft, of major exchange can lead to a confidence in Bitcoin . The regulations led by the government could cause tougher on the Bitcoin industry .
