This might work for people who have not yet know about crypto currency. It is like going conventional but for better. I guess it's not a bad idea at all. Something to consider, to make it believable try to have tech celebrities. Why them? People that are famous with some knowledge in tech will easily be trusted by common people. They then can influence their loyal followers about this crypto. Then their follower will likely influenced their peers. Social media celebrities can also be someone we can consider. Again, choose the one with tech background so people will likely believe with their content. Then afterwards, slowly move to different industry. Do it sowly but steady.
