manipulators want to collect more cryptocurrencies. they manipulate the market and wants market to be dumped when they want to buy. and they manipulate for a rise with good volume when they want to cash out.
That's why if you want to have profits then you would want to think as a manipulator or the whales or the market makers. You would want to know what are they thinking or what their movement might be in this kind of market so that in this way, you can anticipate their movement and you can avoid being dumped and will be not late when the pump comes. One key factor here is having a trading plan always so that you will not be betrayed by your emotions in case there are sudden movements in the market.
If you ask me, that's next to impossible for the vast majority of trading folks as they are driven entirely by emotions even though they themselves think they are quite rational and reasonable. This is how human mind works by retrospectively rationalizing decisions made and steps taken. For example, you make a rush decision on impulse and then you proceed to contrive a reason to explain your actions. With manipulators, it is even worse than that. By trying to guess what's on their mind, you will be only fooling yourself. If your knowledge and expertize is on par with theirs, you will be acting accordingly without ever trying to get into their heads as you won't need that.
