There's nothing solid in the space or something a trader or investor can solely place his mind on which is absolutely 100%. Indicators are right for trades but they don't stop in from losing, rather it reduces losing rate, that's the main reason I have chosen to anticipate in Technical analysis in other to know the dumps and pumps of the market.
Technical analysis for me may not be able to detect dumps or pumps of a coin in other for you to avoid being in the market or investing and losing because it is believed to have happened and you see the occurrence of it to speculate for the future trade you want to enter. Technical analysis help you for future trade but not able to determine when dumps and pump will happening, only you can know that in the telegram group. It also doesn't reduce your lose but you are to take lesser risk and cut down on the lose.
Learning technical analysis is of no waste as it will give you insights with the market.
It may not be the ultimate reason how you can predict the market but having the knowledge of it will give you edge in understanding the market.
Definitely, it won't help you with those pump and dump coins, because they usually don't follow the TAs.
They have their own market movement not defined by any of these TAs.
But in time, you can easily spot pump and dump projects, because of some indications as posted in their social media channels.
