Thank you very much for your opinion, hshan59. You have only taken about 6 out of 18 lectures. As you go further, the methods to safely create real income are introduced in more detail and realistically. The previous lectures are about the basics that you need to know to build income and a stable career, so if you feel that the content related to income is lacking, I hope you will think about it carefully after completing the entire lecture. In this blockchain world, you must first have the ability to make a judgment and trade in order to make income or NFT ^^ Since I have collected core practical knowledge in various fields, if you familiarize yourself with it after completing the lecture, you will definitely find situations where it will be useful in many places. Thank you. ^^
