OP, I agree with everything you said, except for the following:
In my opinion, this holds cryptocurrencies from being a usable and reliable method for everyday transaction use.
Crypto community can simply ignore this "financial voodoo science", as The Pharmacist called it above, and keep moving on.
For those who think, based on their experience, there is a correlation between some TAs and the actual market movements and that that's why we can say that some of the predictions are legit, I would like to remind that if many predictions were made, about anything, there is always a possibility of some of them to come true, no matter however stupid they were.
