I have recently observed no matter how good your TA is, it doesn't always work on alt cos most alt price direction is impacted by BTC price.
When BTC is up all other coin move up. So why spending time on doing technical analysis on alts when doing it on BTC gives you a potential clue of most assets price direction?
Yep mate, that's true !
But anyway Bitcoin price movements don't affect Altcoin every time. I mean that Khabi Khabar gives an indication to raise the price of Bitcoin despite the fact that the fact that some Altcoins do not follow Bitcoin and as a result you may lose. So in fact technical analysis becomes necessary even if it is an altcoin. Technical analysis clears you that you will be safe by taking up trade in the current data, i.e., in this zone. Technical analysis tells you to research of previous data, it can sometimes be wrong or right. Similarly, not only one aspect, but also fundamental analysis is also necessary and if you tell the truth, in Altcoin, Fundamental works better. Because Altcoin follows the event.
It means to say that technical analysis is important even if it is an altcoin, only by doing a technical analysis of Bitcoin, it is not appropriate to make the final understanding of Bitcoin for Altcoin. So according to me, TA is an important factor whether it is Bitcoin or Altcoin.
