"The age of digital money has arrived"
Um, sorry, no. Digital money has been around for quite a while already and was invented by bankers. Cash represents a laughable percentage of all money that is in circulation and a minuscule part of my monthly spend. My VISA is by far the greater part of my spending methods.
The age of funny money has arrived, and it is funny right up to the point where the exchange that has yours folds in a puff of smoke, leaving you with nothing. It's funny to stuff it to The Man until you realize that when you try to purchase something, you're likely to pay more in fees than the value of what you bought. It's funny until you see the conversion value hit the floor when you bought it for $3000.
Yeah, some people have made it big - invariably they got in early. And some people win the lottery. The lottery is more reliable.
Bankers have no reason to be scared of this kerfluffle. There's a dozen cryptoshenanigans available now and no economy is going to collapse because of that. Bankers have other things to do, as in respect their charter and keep track of all the money.
The day I will feel threatened by cryptostupidity is the day Goldman-Sachs puts out its own. But why would it ? It already has all the money.
