Sorry, but that's just garbage TA. It's being rehashed everywhere and it seems that it has even reached people here.
Seriously, this whole space is infested with TA "gurus" that no one even knew about before 2017 and now they think can predict the market? When they are wrong with their 'analysis' they just play it off as the market isn't always following TA, and when they are right they boast about their solid prediction and how much profit you could have made if you followed what they said.
Tossing a coin has been equally rewarding as trading based on TA.
i really think that's unfair. if TA is completely worthless, then there's no reason to engage in trading at all since fundamentals can't be quantified into price---price is subject to speculation and market psychology. that means the only acceptable methods are "buy and hold" or "short to the ground". and since the second choice can screw you on even the scammiest of altcoins, it's a dumb move.
you're conflating "bad TA practitioners" with the idea of TA. a lot of people badmouth TA because they either applied it incorrectly and used bad risk management, or because they see other people making worthless predictions. using TA isn't about predictions---it's about recognizing the trend direction and when market conditions are changing so you can react.
there's a big difference between people who ride trends/use backtested strategies and......the tom lees of the world. people make a living trading commodities, equities, and even crypto. if you think that's done based on fundamental analysis alone you'd be very wrong.
