Do you know how many cryptocurrencies are there now? What are the projects? Where to invest? If at least one of these questions cannot be answered in the affirmative, then this book will be useful to you. In fact, this is a study based on data from the largest crypto exchanges and analytical sites. You can check all the information on coinmarketcap and investing, as well as the sites of the crypto projects themselves, but they do not give the system. I promised myself so many times to do something like this that I realized that the best way to fulfill my promise is to write a book. The book was written in May 2021, and the projects in it are distributed based on the size of the capitalization.
