some time ago I bought an altcoin which has a low marketcap and trading volume. I bought after analyzing using technical indicators. After a while I realized something was wrong. it should be if based on my analysis the coin I bought has entered an oversold period and the price should have started to reverse. but in fact it never happened. the price may go up, but it doesn't last long and it goes back down. then I also bought another altcoin which is almost the same. and again, I also experienced the same thing even though in the end I got profit thanks to long-term hold.
Then I started thinking and wondering, why is it difficult to apply technical analysis to coins with low market caps. unlike bitcoin and other major altcoins whose movements are still predictable. Altcoins with low market caps are difficult and even impossible to predict. whether this is all related to manipulation or there are other reasons that make it difficult to predict.
You gave the answer yourself, if you take the time to study TA, whether this is by using books, articles on the internet, YouTube videos or a mentor, you will get the same information, TA does not work on markets with a low volume, and why is that? Because TA is based entirely on what happened on the market already and making conclusions about it, however when the market cap is low a whale or pump and dump groups can manipulate the coin easily and until this happens it is impossible to predict it with TA, so if you are still interested in trading those coins I will recommend fundamental analysis instead.
