$BTC I remembered this story about a large-scale phenomenon that had a rapid evolution, but which, in my opinion, will sooner or later have the same fate as the wonderful models of the two mathematicians: crypto assets. These were born just a few years ago, in the scale of history. The domain "bitcoin.org" was registered in August 2008, less than a month before the collapse of Lehman Brothers, and the paper "Bitcoin: A Peer-to-Peer Electronic Cash System" was published electronically by Satoshi Nakamoto in October 2008. (In fact, Satoshi Nakamoto does not even exist; under this pseudonym presented themselves the mysterious creators of the first crypto asset; but does it really matter such details if the love is great?) Thus began the crypto adventure.
