It's great that you're interested in learning more about crypto. I also suggest purchasing Udemy Courses, and you will surely get some fun time with cryptocurrency. However, you must select the proper one among a large number of Udemy Courses. Just concentrate on the reviews and select the ideal one for better learning.
One question, have you gone to that academy for trading? they focus on technical analysis and learning from indicators? I ask because one day a woman came to me offering me that course, and she told me that they did learn about trading there, but what they know most is technical analysis without passing because they teach them to think about what can happen, there are no theories, there is nothing, they are only dedicated to technical analysis, and according to a book by Malkiel Burton, trading in this way does not work, neither with only technical analysis nor with only fundamental analysis, so I think that if the academy teaches how to think to his students, it is the ideal.
