If i were an American and financially stable, why not.
But it's more likely people (who are financially stable) will spend their $1200 on non-essential goods rather than investment since people already have mindset it's bad time to do any investment.
I think it's not right that the money is distributed this way. If one's financially stable, it means one doesn't need these $1200, so it would make sense to give this money to those who need it more. So as much as I'm pro-crypto, I don't think it's right to spend the financial package for combating COVID-19 on investments of any sort, Bitcoin included. As for the $1200 chart, it can be that we're missing something and it's the confirmation bias getting the most of us. Correlation is not causation, and people who get the package might invest a part of it while those who don't might feel like spending $1200 for some reason.
