1 - TA won't predict the future. No one serious would ever claim that.
I disagree with that, because I've heard many people--all very serious and earnest--claim just that, that looking at charts will tell you exactly what's going to happen in the future. That's basically what TA is.
Yes, I think TA is bullshit and I've said this many times. Fortunately a large part of Wall Street has realized this as well and don't employ as many technical analysts as they used to. Fundamental analysis is the only way to go in the stock market.
In crypto, I would think that "fundamental analysis" in the form of just looking at the news is useless. Why? Because everyone else is doing the same thing and using the same strategy, plus news can be inaccurate or downright fake. You may as well be trading on rumors. In fact I've also said that there's no such thing as FA in crypto, because there aren't any real fundamentals to analyze like there are with stocks. All of the metrics like P/E and so forth that you have in the stock market are all missing in crypto. The only thing crypto has is supply and demand, and the supply is always known, so the only thing to analyze is demand....and how do you predict that accurately?
