There are many ways to learn Technical Analysis for crypto, the easiest way to use the Google search engine. Can also learn from social media,
now many groups have opened Technical Analysis training. Can also learn from the YouTube platform, or can also follow a seminar on cryptocurrency.
If you have a cryptocurrency community, you can start learning from there. Just choose one that is comfortable for you.
You could also use trading itself in my opinion because when real money is involved all the analysis will be applied and you will not be half-assed about it because you will experience real loss, you might want to be sure what you are doing because this involves real money, the risk is high but the reward is bigger because you eventually learn along the way and if you are a lucky newbie then you might also earn along the way.
I agree that you would learn a lot more by trading yourself but you are replying to a completely different question actually. I mean the OP asked for how we can learn about technical analysis that is how to know the structure of the coin like the scalability, functioning and other important aspects.
In my opinion the best way to learn technical aspects is actually first read their whitepaper and understand the structure and how they are proceeding with their project, in my investing experience of a few years I am so good now that a copied or forced whitepaper is just peanuts to detect for me and I never invest in a project where I do not see the commitment from team and a copied whitepaper is just the proof of how lazy they must be.
Another thing you can do is to read about their team and learn about their experience and past projects while sometimes you can learn a lot by reading some articles on medium and other sources.
