In situations of economic crash, it is smart to adapt and switch to means that will provide easy ways of patronizing other services and items without having to spend much money. It is not always a matter of waiting on the governments to bring solutions. There are many online jobs available for those who permanently or temporarily lost their jobs during corona virus outbreak.There are also other means of selling and buying using cryptocurrency and other forms of digital money or even barter trading with neighbours (this must be done with precautions because of COVID-19)
I don't think that is a good solution.
Not all of us have a cryptocurrency and not all of us will be able to accept and use it as payment. Not just because they do not know how will they use it but because only a few of the stores or merchants accept it. Though it is really a good time for people to adapt and use the means that we have the internet, there are convenient and better ways to earn using that.
