Ah. Technical analysis. One of the most controversial topics when it comes to trading.
There are people who says that TA works, then there are people who say that its pure BS. Personally? I don't think so. I think that the cryptocurrency markets are very easily manipulated by whales and news alone, and I'm pretty sure TA can't predict those manipulations, but I also think that TA helps to only a certain extent.
What combination of techincal analysis do you really use?: I'm not exactly sure, but what I know is that people has their own ways of doing TA; that's what I think due to me watching a good number of videos on youtube of people demonstrating TA.
So what do you think is the most useful analysis in crypto? The crystal ball I suppose. Dude even in stock market whales exist, don't demonize the cryptocurrency, saying that easily manipulated, technical analysis is useless etc is baseless. TA is only a guide it will help you give a clear option if you want to take the risk or not and even you have given a good advise it will not guarantee you success. You still need supplementary analysis for your TA.
