You will have different opinions regarding this particular question you are asking.However, your question is unpredictable to me, as we all know that when we compare the adoption of bitcoin, the gain in the world wide current is far greater than it was in the early days of bitcoin, so as we are getting more adoption, some nations will start showing concern about people who use bitcoin. But still, even if bitcoin is not accepted as a dominant currency in the future, people will still be using it, which means bitcoin did not fail.

However, it will be hard for bitcoin to overtake the currency people are using. The adoption of bitcoin will only get more popular with a new generation that is quickly accepting it, so you can see that the more people adopt bitcoin currency, the more it will make sense during discussions about this kind of issue.
