Well for some instance, people are now doing online transactions yet using fiat money or their countries' currencies in doing so, but yeah, bitcoin can also be used specially of those who have it. I use it on paying my bills, buying loads, online shopping, and etc so, yeah it is really indeed a solution for transactions while we are on this pandemic.
I keep thinking about this idea but somehow the ignorance of most people will make this too impossible. I mean we cannot simply transact to every one since not every one is capable of sending and receiving bitcoin, there are only a few that use it for their daily expenses. I vote for bitcoin, as an alternative to fiat currency during these days to avoid physical contact because of the virus.
It can be useful when buying online instead of using credit cards to avoid backcharges, but there is only a few merchants currently that accepts crpyto payment method.
