But we don't know if that is right or not. Bitcoin adoption still on progress, but people use the other payment method. I guess they still use fiat money to make a transaction, and if they use a digital payment, they will use something that they already know before. Unless bitcoin already accepted as the payment method in one country, people will not use bitcoin to pay something, but they will use another payment method. We know that there are so many digital payment methods besides bitcoin to pay something or buy something at a local store in some countries.

So Covid-19 is not the only one of the reasons for bitcoin adoption.
