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.
The reason being that most altcoins are short term/pump and dump projects that can pump and dump spontaneously, most Investors do no research when they want to invest in some altcoins, they just buy when it's low and hope on luck for an appreciation in price so they can make profits. The reason why its movement is unpredictable, is the same reason why it is regarded as being very risky. Having said that, many of such altcoins can be manipulated quite easily, that's cause sometimes an individual could own more then 50% of the coin, and whenever such person dumps, that's the end of such project. But that is not the case with Bitcoin, it is a long term project with a very valid use case and a demand that will continue to grow, that is why if you're not making profits on the Bitcoin network the time you invested, you're advised to hodl, as more often than not, you'll make profits along the long run.
