Well, considering TA's is just a guide and something a thing to look at but relying alone upon TA isn't good at all. We know its market behavior and can't think that the market will have a steady flowing trend that TA's will be right all the time. It is our self to adjust from how the market works and changing our trading strategies will work well otherwise, we are just hanging on the train.
I'm not a big fan of TA when it comes to prediction. I can say that I enjoy looking at them a lot and reading them and most of my time reading trading news is TA anyway but that is always just looking at patterns of the past and understanding that especially in crypto/Bitcoin you can't really apply TA until the market is more mature, which will take many more years.
