Ok, it is not Bitcoin, but if more merchants using Fiat currency can switch over to Bitcoin, you might see less infections. The reason for this is simple, because the Corona virus can be transmitted from person to person via cash being used on a daily basis.
People can also do online payments with Bitcoin to avoid handling physical cash and thus avoiding infection. It can also prevent people from being infected from a host of other viruses and bacteria that can survive for days on physical coins and notes.
This is just one more reason for people to move away from physical payment methods and shifting to a cash-less financial system in the future.
This is actually a good idea because with all the realizations from the present virus, people are now in extra careful and cautious in prioritizing their health. Electronic payment is advantageous since it is less hassle especially for busy people, saves time and effort, and most of all, can reduce the risk of being exposed to viruses which can be transmitted from object to person.
This will result however in putting pressure in banks or any payment system to accept crypto especially in small-scale businesses. I also think that if this is the case for China, then, the use of crypto can decline if the reason for its use is gone (when the virus is completely gone). But if the people learned from that experience, then little by little, the emergence of bitcoin will continue as long as it will be carefully monitored and observed.
