Ive learned a lot on youtube tutorials and I can say its really worth it, but of course you should not just depend on that since a lot of sources can be found easily. Books and seminars can also help you, learning TA should be done first if you wanted to become a good trader.
Are there really that many worthwhile cryptotubers doing TA on youtube? The only thing I see them do is rehash the same obvious patterns over and over again, and then just move their target lines because the market wicked above it.
I can do that too. It's not hard to draw triangles and use Fibonacci retracement and then wind up a whole story around it pointing at moving averages. Too much noise and very little signal.
It's basic understanding, but with how people don't know anything about trading at all, everyone with that basic understanding will look like an expert to you. It's not for nothing that people pay for their courses and signals....
