I don't think people are caring about bitcoin than the Covid-19! In this world, most people use the Internet, not because of the Quarantine time, rather every day in their life! Covid19 did not bring a bunch of new internet users! So, it's not that what you are thinking, mate! Therefore I don't think people will promote about Bitcoin money, who are did before, they will do now! That's it, it's not a great time to promote bitcoin widely, rather this is the time when we should spread awareness about Covid-19 so that people stay home and fight the Coronavirus!
You are right, basically, the internet is widely used every day, its intensity increases when most people do work from home which requires that they are connected more often with the internet for communication. As with investment, I think some people will focus more on how to survive in this critical situation, share with others, and spread goodness. It's okay to spread education and information related to BTC as an alternative to getting additional income, but we know that the crypto world is not something that can be learned instantly, it takes time, right?
