One of the main features i like about bitcoins is its transactions are anonymous. But that makes me wonder if a time will come when it will be banned worlwide. It has started in many countries.
Highly doubts, I just like to think positive about bitcoin. Yes, few countries trying to ban and on the other hand few countries encourage to legalise bitcoin. I have heard even few countries trying to learn about blockchain technology how its working. Those are really want to ban they have lack of knowledge about blockchain and they are worried about their centralized banking system. If worldwide government try to ban bitcoin then it would be use on black market. So crime rate would increase overall. That's why I don't think it will happen near future.
