Without the order book, how in the world are you supposed to know where the big buy and sell walls are and at what depth your limit order is placed? The order book is invaluable for traders.
You mean without the whales' influence? Invaluable for whom? Only the fucking whales profit from these walls.
Whales are part of the market and since you can't beat them, it's better to join them right? I would rather be riding the waves with them than getting crushed under their weight.
