TA is mental masturbation and a way for Youtube dorks to get views. Charts fail to account for a lot of things and the Youtube guys that rely on them should openly admit that the only way to understand patterns is in retrospect.
For example, spoofing and leveraged trading have been around for a while but not at the high degree they're being used now. History can't account for those things to accurately predict using a chart comparing 2017 to today.
Institutions also don't tend to use platforms to trade BTC and eth, so as not to cause ripples in price. That's a newish phenomenon as institutional investors have entered into the space.
