No one actually knows. The prohibition of the ICO in China was very unexpected and came out of the blue, thus questions like these pose a threat to bitcoin's price. When China banned their ICOs in their country, it dramatically decreased the price of bitcoins from $4200 to $3250 in a matter of weeks. Fortunately, bitcoin regained its price after a month, but there is always the possibility of a country, doing the same move as China or even worse. But be reminded that whenever a country prohibits or bans bitcoin usage, there will always be an announcement from a country that will supersede the negative effects of bitcoin banning (i.e. Japan announced that they welcome bitcoin utilization in their country).

Of course no "country" is scared for its citizens. The only real reason why the governments might ever be banning crypto currencies and related services is because they cannot parasite on it (i.e. steal money from the people) and they usually substitute this real reason with a fake reason of some "preventing money laundering/terrorism" or "protecting the citizens" nonsense.

the government forbids anything in the country because it wants to protect its people, if bitcoin is safe, stable and will benefit its people, the government also will not ban it

Maybe if bitcoin has a bad effect of course the government in other countries will also follow what is done by countries that have banned bitcoin. one of the keys to the solution is to provide regulation on bitcoin so that the bad effects of bitcoin can be controlled by the government. so the government will not be concerned about decentralization and anonymity again but I do not know bitcoin users will agree or not about regulation for bitcoin?

Did they succeed in banning it completely or people are still able to use bitcoin in China and the likes? I don't think any government will be able to effectively ban bitcoin because it's not in their hands,. All they could do is to enact and enforce stringent laws against bitcoin users and exchanges and make it difficult to use but i think people will still sneak behind and use the dark web and other places.

governments are so much banning bitcoin lately, as much as finally beginning to regulate it. this was inevitable folks, and we got here a lot faster by attracting attention to ourselves, via the ICOs, and the wild bubble. At these price levels, capital flight just isnt the only issue; you can greatly facilitate money laundering with cryptos. the ico circuit has almost certainly accepted some dirty money; which has gotten washed into the crowdfund, and came back as shiny new tokens.

this doesnt necessarily have to be an intentional thing, but it is definitely happening. 

There would be a chance that other countries like North Korea and Russia will ban the use of crypto currency because these two nations share the common interest with China. I think they are scared of it because it is something so powerful and they know that cannot fully control it. No doubt they don't want to waste their time and resources because of the risks that bitcoins can deliver.

possibly could happen! but bitcoin will still exist and continue to grow, take samples after being banned in china bitcoin price is even higher

as far as i know, China never tried to reduce the value of bitcoin, the deep dump of bitcoin in September was just a by-product of banning ico and exchanges and what Chian done is to control group events and increase financial security
