First and foremost, you need to know that I like cash. The feel of a real coin or a dollar bill in my hand is tangible and powerful. But the latest pandemic fears have us all worried about money transferring the Covid-19 virus; and that is a real fear. I wrote this article early in the pandemic, and it is still relevant today. https://bitcoinmoneyman.com/blog/2020/09/16/is-it-time-to-abandon-using-cash-money-and-what-do-we-use-instead/ Update: It is highly unlikely that you will catch Covid from handling paper money, unless a Covid positive person just coughed on your money; Covid is most likely transmitted by airborne particles. Despite this I still err on the safe side and clean my money and wash my hands a lot. I suggest that you should too.
