Well for me, when I read first the question, there is only thing that comes into my mind that answers this question, in which how can we make crypto into viral, and that is, make and spread several fact news, announcements and updates about crypto currencies which positively influence the community. A good great and positive news will make more people to become more curious regarding the crypto and will eventually engage to it.
If you want to make cryptocurrency go viral and spreading several facts about it you should use the power of social media which help you to spread the news about cryptocurrency all over the world. I always use social media to spread and for you in what way you will do to spread the facts about cryptocurrency.
