It is always good to learn about price action before investing in cryptocurrency. Learning will guide your judgement in the market and prevent you from making decisions with instincts alone.
I see a lot of people complain about the recent dip in the market and I am surprised. Because if you know about price action, you would see that the signs were obviously there before it all went crashing down. On the daily time frame, Bitcoin broke structure and retested several times before heading down. The market warned you, but you didn't see it.
Learning to read market signals is obviously better than not being able to read them, but I dont think that it woul allow you to realistically avoid all or even most of the dumps in crypto. The main reason for losses usually derive from poor knowledge of crypto in general. The difference between knowing crypto vs knowing crypto markets is that if one takes into account that crypto is unpredictable and volatile then one can avoid panic-selling.
I believe that a person who buys into crypto with money they are also comfortable losing and believes in the long term rise of crypto, will do better in the market than a person who tries to fully understand the market and avoid all crashes while simutaniously riding all the highs
