I am not butka, but I believe I understand what this user and Anthony Pompliano meant. Some might think that cryptocurrencies are designed for the Internet of things, basically. This means that devices communicate with each other, send and receive valuable information without human intervention, so that in the end humans get a nice and smooth life. A simple example of how it can work that just came to my mind is that when someone gets in the car and intends to drive while being drunk, an alcohol consumption detector near the wheel of a car can measure the alcohol and send signals to some mechanism that will prevent the car from starting. That mechanism, in turn, can send a signal to the sound system to provide explanation to the driver on why the car won't start. All these transactions might need a cryptocurrency to get performed. IOTA is the most famous example of a crypto designed primarily for the IOT.
My view on this matter is that some cryptos are designed for device communication but most of them are meant for humans, and cryptos are not that hard to grasp. I also agree with deisik that most of people use fiat without understanding it.
