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?
Yes, it's true that when the price of Bitcoin rises, almost the majority of the top altcoins also follow the rise of Bitcoin, but that doesn't end there, because it's still different when you perform technical analysis or fundamental analysis.
Particularly if you are doing trading activity, where you really have to use to consider so that we can determine if the rise and fall of the price of the coin we hold will go, and it also depends on the timeframe that we will use. But the market is still unpredictable.
