I think Bitcoin will dead if every country decides to ban Bitcoin permanently. Then, there will be no more people using Bitcoin because they might be arrested in this condition. And bitcoin can also be dead if there are a new cryptocurrency which is more profitable, more advance and can fix most of the bug of bitcoin. In the future, there will be more cryptos qualifying these facors.
"

Come to think of it what will make all country to ban such virtual currency if, it's beneficial to them?
Thanks
