No they are not always good. They are layer walls. They create the pressure to drag price down not cushion it. The instos play both sides. They will layer the sells and buys at same time to drive price. Essentially it is a rug pull as they move the buy wall down as go, it doesnt hold in place.
That buy at 770 was was moved and price went up today, put back in its falling again. They will be stacking the wall with what they gain on the pump then shorting it on way down, they will be layering in buys all the way up to wall and move it again if feel need to steal more. This should have corrected as massively oversold yet hasnt meaning they are still purposefully manipulating the price. Seems to be still some silly people panicking and selling into the thieves layers.
