I think cryptocurrency is far from the first thing that comes to the minds of government when they hear "contactless payment" - they would likely think about bank cards, PayPal, GooglePay and so on. There might some small chance that it will indeed lead to crypto recognition, but I think at times of the crisis no one will have time to think about crypto. And potential adopters might be scared off by crypto's volatility, as we see that crypto markets aren't doing well now.
You have a point. Not everyone would want to take a risk on crypto especially when there's an issue like this. Like what you have said, there's a higher possibility that they would go with card payments but crypto payments can also be their option if they have or they want to. It's not necessary that they will shift from fiat to crypto. But since Korea has recently legalized crypto, it will give crypto a higher chance to be noticed by Koreans.
I have been never been bug by the virus not until today when suddenly our country has confirmed 35 cases total, mix Chineese and local citizen, some are panicking already since this could also mean that the contact to contact is real and it could already gone too far. For now we cannot feel the tension because the numbers are small, sooner or later when it would be more than hundreds and counting then the country will be in a statee of calamity again, just recently it is because of a Volcanic eruption. If I were to ask- I would change all my money to crypto just to make sure that my valuable assets are safe.
Even with the low number of cases, it still bothers me because of the incompetency of our government. Unlike other countries who can handle the situation very well, I'm afraid that this small number of cases will double in just a short period of time. We have limited test kits and not everyone is capable of handling the expense of going to hospitals. Look how our citizens act on this kind of situation, instead of helping each other, they're hoarding necessities and selling it at double price.
It's up to you if you want to put all of your money in crypto. But what I'm just trying to say is that crypto can be an option or alternative to lessen physical contact transactions and holding paper bills that have various bacteria.
