...I believe that it could be a win-win situation for Bitcoin and other cryptocurrencies in the Blockchain space. Unless governments decide to start rolling their digital currencies to the world, everything will remain likely the same as it is today.

I don 't understand why there is such a fuss about fiat money. I think that many people have credit cards , and accordingly, there is no need for such people to pay with fiat. Therefore, from the point of infection spread, there is no difference whether you will pay with a credit card or make a payment with cryptocurrency.
That will happen in the country which many people have credit cards, but not all people in that country will have credit cards. People still use fiat, but in these situations, they will hard to pay use fiat because many of them are staying in their homes. We don't know how the virus will spread, but we can prevent with care, and we can reduce direct contact with other people.
I think that if a person does not have a credit card, they will not be able to use cryptocurrency. Because the presence of a credit card indicates the financial capabilities of a person. Therefore, such a person may not have the necessary minimum for calculating a cryptocurrency such as a smartphone, because a push-button phone will not be able to help him with calculations.
