Here in my country, I didn't felt that Bitcoin usage has increased since the pandemic. I'd say that online transactions had increased massively because of the fact that the physical cash can be a carrier of virus but base on my experience, I saw many people here using e-cash rather than using Bitcoin. People right now are paying what they are buying online using digital cash and not Bitcoin here unfortunately because many still don't know how to use it for transactions.
In my part, Bitcoin helped me too to buy some things but I don't use it directly as a payment but I'm converting it into digital cash where that is the one I will use for payments online.
