Blockchain the transaction record is immutable and sure can be shielded
—————
Us older folks don’t consider electronic “ money” as money. It depends on electricity ( and other weak links), when that fails, e money fails.
The hurricane in Florida ( and grid down in Europe) illustrates exactly how worthless e money is during electricity failure. The only thing accepted then is cash, a tangible that is held in your hands. Due note Spain and other areas locked up tight, no buying, no selling until electricity was restored, about three days.
The electricity argument?
95% of dollar based transactions are electronic.
If the power goes out—most people are not buying. And…if the power goes out, across the nation for any amount of time we will have much bigger concerns than bitcoin or dollars.
There are lots of arguments to be made about cryptocurrencies….but a power outage isn’t one of them.
