You are right. In failing, you will learn more. Failing or losing is unavoidable because we are not perfect and we will only grow through our mistakes so that we can learn from it and then do better next time. As for the books, it would be better for OP to start with babypips.com because it is a comprehensive site wherein you will learn trading slowly so that you will not have an information overload and be more confused. You are like going to school all over again through that site. It may be about foreign exchange but still the trading method is there and it is applicable to cryptocurrency market too.
