You may be right. I do wonder if the cashless trend will continue.
I also wonder what the black and grey markets will do in a "cashless" business world. I go to sporting events from time to time. Will scalpers be asking you to enter your pin number. If you have extra tickets and a scalper wants them will you need to pull out your "Cash" app on your smartphone or the bitcoin app? Last night I sat next to a 70's+ couple and I don't think they have a smartphone.
I wonder if transactions will split our economy. Will some move to one side that deals with online transactions and the other side that deals with barter, and/or precious metals. If there is no cash, negative interest rates are possible and bail-ins become a lot easier. I don't think everyone is going to roll over for this. IMHO
In case you can't tell, I cash out much of my paycheck and try to do most of my transactions in cash.
PS: The value in these coins is the utility of the copper, not it's tender status.
