There are no "manipulators", there are simply big players who have the opportunity to influence the market, and obviously take advantage of it.
If we were able, we would do it too.
For what concerns us, we can only try to understand in which direction the "manipulator" will move the market, and go after it.
These are the game changers. They can do what they want. When they realize that now it is the time to bump the market, the price will suddenly go up without any reason and when people invest their money, the price will collapse again without any reason. Small investors will lose their money due to fall in the price. Manipulators buy on low price and sell on high price to collect the money.
