You are right. Covid-19 really opens the door of digital world and more so on digital currencies. But I believe that cryptocurrencies won't replace our traditional ways of financial management or the fiat itself. Aside from this high technology-driven world now, there's still a lot of places around the globe that is so uncivilized and have no signal, internet connection nor smart gadgets and they have no knowledge about this IT thing here. So, for me, digital currencies is for the cities only, and it can't be used by everyone, even during this pandemic.
What I find interesting is how hard cash (paper bills/coins) has greatly diminished in use at least in the USA. 'Contactless' transactions is the preference now so it should benefit crypto currencies in the end. For routine purchases I still favor the credit card for the mile$, but if I was a cash or debit card user, bitcoin on a digital wallet might have a value proposition if adopted/supported by vendors. Hopefully sooner than later.
