I recommend that you read books of market speculators, since technical analysis can be learned anywhere, it is first that you learn to analyze the market, that you learn the phases, that you understand how it moves and the possible causes, most of the academies They teach the same indicators.

 Among my favorite books, I recommend: Wyckoff, Livermore, Warren Buffet, which apply to the Stock Market but are equally applicable to the Bitcoin market. Once you start to understand the market, if you study technical analysis anywhere, on YouTube there are many free courses.
