Well, it seems a lot like quite an imaginary thing. The way I see it, maybe the best comparison would be the Internet, but at its beginning (20 or so years ago) when the majority of people didn't understand what it is and how it exactly works.
I believe, when cryptocurrencies start to be used more widely people would start getting it.

In other words, when first money in the form of real coins was introduced to people who by then were used only on trades like 10 chickens for 1 goat or vice versa, I think they didn't get it either. They were probably asking themselves how to use that piece of metal as well as how come it has some value (even if the coins were made in bronze, silver or gold).

The very same question, most likely, appeared in the heads of people when those coins were replaced with paper money, as at the and it was and still is only a piece of paper.

Another revolution in understanding and accepting the new payment method, I believe occurred with the introduction of credit and debit cards.
I'm sure nobody could exactly imagine and figure it out at the beginning how this piece of plastic can replace the paper money they were familiar with.

With the technology development today we have virtual coins or crypto coins, and now we have to learn how to understand, imagine and accept the fact that in coming times most likely our paper money, credit & debit cards would be replaced with a piece of code that represents a certain crypto coin.

That's the way how I see the crypto world at the moment! 🙂
