Thank you all for your answers.

What I want to note in this matter. I'm talking about money and only about them, so the answers that any money is good or doen`t matter what kind of generation they are, do not answer my question. For example, all computers in principle do the same job, however we distinguish different generations of computers according to their technical capabilities. Nobody will say that old computers are worse than Solid-state drives (SSDs), because for their time they were the most technologically advanced. But time has passed, and today old computers are either thrown into the trash, or put into the museum.

So if you consider paper money as old, and all the crypto-currencies as new, then this is also an incorrect answer, since the question is only about digital crypto-currencies. Why do they write that they are "the money of a new generation" when issuing some altcoins, and other altcoins
say nothing about it?

What is the meaning of generations in digital crypto-currencies?

Look: when I read a description of a particular crypto currency, I always meet this phrase "our crypt is money of a new generation". That's why I decided to ask the community what is the point of these words, or are these empty, meaningless words used only for advertising purposes?
So, once again I clarify the question: What is the meaning of the generation change just for digital crypto-currencies?

I write for the first time on this Forum, so please be lenient towards me. Especially to my English.
When they talk about future money, for some reason "money of a new generation" is often added. What do these words mean "the new generation" as applied to money? How does the "old generation" differ from the "new" generation?
For example, in computers, the generation change is understandable, and in the field of money it is incomprehensible. Can someone intelligibly and intelligently explain to me the difference between generations of money?
I think that this question is actually much deeper and more interesting than it seems at first glance, because it gives us a deeper understanding of the very essence of money.
