...Some of the people don't want to use the physical money or the paper money because they know it is dirt and came from the different people that already have a virus and as a person do you make any sanitation in that? Of course, no so why not use the digital currency and there is no aspect of having a physical interaction on the money and the came from the receiver and sender of the money...
I don think this important at all because today we can pay overall and for everything, without even touching real paper money or coins. TBH I don't remember when I have paid with cash last time?
I have multiple banking apps on my phone, in my watch, and even in my fitness thing. One can pay using cards and all is contactless at least here where I live.
This didn't happen yesterday and I use it already a couple of years. I am sure that this will go even further and finally, there will be no need for real money at all, I assume.
I don't remember when I had to take cash from ATM the last time. I know that a couple of years ago, I was constantly by the ATM withdrawing funds, but from some time I don't do this anymore.
That is why I think that your speculations about viruses are totally insignificant and have no impact at all on BTC and that it is or could be a save heaven in the future.
