Payment for goods and services through cash can transmit Corona virus, doing transactions through bank, especially cash deposits can also transmit the virus. The safest way that we can create values and pay for goods and services during this time still remain blockchain and those selling off at this moment are doing so because they did not spend time to study the Blockchain technology and how it works.
The problem is that not many people are aware of bitcoins and how to use them. In times, where cash dealing can be dangerous to spread the virus by touching the physical notes, people can opt for online payments through debit credit cards etc. If Bitcoins were massively used in these situations then we could have pump in bitcoin prices, but the opposite of that happened. The reason is that bitcoin is mostly used as an asset and not used as a currency.
