Do you know how many cryptocurrencies there are now? What projects are there? Where to invest? If you cannot answer yes to any of these questions, then this book will be useful to you.

You can check all the information on coinmarketcap and investing, as well as on the websites of the crypto projects themselves, but they do not provide a system. I promised myself so many times to do something similar that I realized that the best way to fulfill my promise to myself is to write a book. The book was written in May 2021, and the projects in it are distributed based on the size of capitalization.
