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?
Most time it plays out well but sometimes trade can go south if you ignore analysis on particular alt you wanna trade. So my advise is analyze both to be a bit safe
Really? I think this means that the OP have only done something wrong and that is why he believes that TA in alts are not working and I'm with your side with that because if we think about it, there are crypto traders here that are always doing a TA and trading is not always limited in Bitcoin but there are plenty of altcoins and tokens to choose from, though maybe they can also include BTC on their analysis.
I think luck is also involved here, so even if you don't try hard and do an analysis, the market can still favour at you, and the other is if you do your best in TA, sh8t still happens but it does not mean that you won't do it anymore because most of the times it is still beneficial.
