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.
sometimes a trader does not understand the signs as you mean, many traders I see today who do not understand about candlesticks or market charts. even though in the graph there are all signs, whether it will go down or up, many people don't understand that so many complain when they feel a loss
