Hands-on Elixir&OTP: Cryptocurrency trading bot is a practical Elixir and OTP ebook built around the theme of a “cryptocurrency trading bot.” It focuses on building a non-trivial Elixir application from scratch and gradually evolving it into a tested, fault-tolerant concurrent system. The website offers a free online version, with PDF/EPUB editions available for purchase via Gumroad.
Based on the available text, the book covers setting up a new project, orchestrating OTP processes, progressing from a single GenServer to supervision trees and multi-layer supervision, and exploring the practical boundaries of functional code. Reader feedback also mentions backend topics such as WebSocket, PubSub, mocking, and databases, so this is not merely a “trading bot” tutorial; it is closer to an Elixir backend architecture guide taught through a concrete business scenario. The format is primarily an ebook. Although the text mentions the author’s YouTube videos, there is no indication of live sessions, 1-on-1 instruction, or a structured recorded course.
Pricing information is limited: the online version can be read for free, while the paid PDF/EPUB version is sold via Gumroad as a way to support the author. The page does not disclose a specific price. There is no sign of any certification, completion certificate, exam, or employer-recognized credential, so it is not suitable for learners whose main goal is to obtain a certificate.
Author Kamil Skowron describes himself as having over 10 years of experience in enterprise systems engineering, with experience using PHP, Node, and Elixir, and he emphasizes learning by doing. The FAQ clearly states that the book is intended for readers who already have a basic understanding of Elixir & OTP and want to learn how to build non-trivial systems. Complete beginners may find it smoother to first study Elixir syntax and the fundamentals of OTP before starting this book.
The main strengths are its strong project-driven approach, low barrier to entry thanks to the free online version, and focused coverage of GenServer, Supervisor, fault tolerance, and loosely coupled modeling—making it well suited to engineering-oriented learning. The downsides are that support services are unclear: there is no visible homework review, community Q&A, update schedule, or detailed pricing. The trading bot theme may also mislead readers who are only looking to learn general backend development. The available text does not provide information about access from China. Gumroad may involve some uncertainty in terms of payment and accessibility, so it is advisable to try the free online version first. Alternatives to consider include the official Elixir documentation, Elixir in Action, Pragmatic Studio, and relevant YouTube courses.
