Some people have the intellectual capacity of a goldfish.
I'm actually kind of at a loss for words, because it represents such a fundamental ignorance of history, economics, and language that I'm not sure these people actually live in the real world. Perhaps they're kind of pan-dimensional beings that just kind of accidentally step into our universe from time to time and are totally bewildered by everything they see.
I guess the best I could do is point these sorts of people toward the information they'd need;

Certainly you're not one of these people right?
I am one of those people who knows that there are unabridged dictionaries that show many different definitions of the work "fiat." I am also aware that people who study economics have written articles where they use the general definition and discuss Bitcoin as "fiat" currency as opposed to the more specific "government fiat" where there is no ambiguity.
I am only mediocre in English though. I got a master's degree in Physics and bachelor degree in Physics and computer science from Rutgers so I spent most of my educational time doing math formulas and writing code.
Do you have a degree in meme-based debates on reddit?
