Payment for goods and services through cash can transmit Corona virus, doing transactions through bank, especially cash deposits can also transmit the virus.
Paper banknotes and coins are, without any doubt, one way of transmitting the virus, as it has been proven that it can survive up to 9 days on different materials. So at this point it would be very wise to avoid paying this way, and to use cards and online payments more if possible.
Unfortunately buying basic lifestyles with crypto is still a very rare exception, and people have no choice when it comes to having to buy food, they have to sell crypto even if it means a loss in terms of investment. It would be ideal if everyone could pay for their goods and services online and receive delivery to their home address, which in a particular situation would definitely reduce the spread of the virus.
I think that after this epidemic, China will accelerate further the development and introduction of its crypto (allegedly working for years on that), and maybe some other countries will follow. But even cashless society as Sweden where 98% of all transaction is digital are not immune to virus, data from 2 days ago is say there is
461 confirmed cases.
