The title you indicated and the description that was said for fiat contradicts. Your title says that there's no value but the description that's being said on fiat is this.
Why fiat is a digital currency
Bitcoin is a digital currency, just like the fiat currency has digits all over the bank. When the visa card was established people didn't understand it's usefulness when the Government wanted a cashless community the same as bitcoin just that we need fiat to get bitcoin unless we earn it like other money, today people now use cards to book flights, hotels, etc
Bitcoin was even compared to fiat which means to say that bitcoin doesn't have a value. I don't understand that description or the author is playing blind about the current value of bitcoin. And it's not suffering if bitcoin doesn't get popular, it's starting to become popular and we don't actually have to think about its popularity because it's already published and covered by mainstream medias.
