This book is about cryptocurrency trading. It is assumed that you are new to cryptocurrencies. As such, we will walk you through a comprehensive introduction to what it is, how it works, and from there you will be able to understand the material on how to trade it. Cryptocurrencies use several terms in the common dictionary of analog age. From the notion of 'currency' to the notion of 'blockchain', to the notion of 'payment' and 'ownership' and to seemingly unrelated notions such as 'mining'. Here and now I will tell you that none of these terms are used as they used to mean, and in a moment you will see why. We will show you what they really mean and begin to understand how to trade these currencies and the tools you can use to approach this market competently and confidently. We'll also show you how to look for opportunities and even use algorithms to trade fast instead of manually clicking the buy or sell button or drawing lines and graphs manually to predict movements. We'll show you how it works, but we also discuss software that can do it at lightning speed.
