The Associated Press reported last week that there is a boom in bitcoin use — in Iran.

“Some observers have warned that cryptocurrencies could be used to bypass the Trump administration’s sanctions targeting Iran over its unraveling nuclear deal with world powers,” explained AP.

Or, as I’ve said in past columns, these cryptocurrencies allow rogue nations to get rogue-ier.

And someday one of these countries will use cryptocurrencies to pay for attacks on the US. And that, I’m sorry to say, is a real possibility that I will explain further in the future.

That’s why these fake currencies will eventually lose the confidence of world investors and will ultimately be worthless.
