One way is through media. We can used it as one way by showing people that bitcoin has a lot of good things to offer. News, tabloids, and announcements has been saying that the market price is falling. On the other hand, reporting good things and its benefits could make others change their views about cryptocurrency. If other countries could legalized bitcoin, then I greatly believe that it is because they see the good things about cryptocurrency. Therefore, the public would have a high possibility to see that as well.
